The Excitement Over Digital Photography

Digital photography is generating excitement in the world of nature photography unlike anything else in my long career. I have always cared dearly about obtaining quality images. As a result, I missed the early stages of the digital revolution because it didn't make any sense to buy cameras that were far more expensive than top of the line film cameras, only to get inferior results. But, by 2003, the best digital cameras were coming close to the quality offered by the best slide films. Perhaps they weren't quite as good as Fuji Velvia 50 slide film, but digital capture was excellent and becoming widely accepted by photo buyers. When the 16.7-megapixel Canon 1Ds Mark II became available a year later, digital capture was at least as good as slide film and more fun too.

Why Take Nature Photographs

We all have reasons for photographing nature. Perhaps you are more interested in winning a photo contest at the State fair or camera club. Perhaps you want to get published in a calendar, magazine, or book. Perhaps you want a beautiful web site or gorgeous prints on the wall. Perhaps you love digital cameras and computers so you make images to use those tools. Perhaps you love being in natural places and making photos gives you an excuse to spend time enjoying natural events. You may photograph for fun or hope to make some money from your images. All of these are valid reasons to photograph nature. Most likely your reasons for taking photographs of nature include a combination of these.

The World Of Digital Photography

Digital photography is a new way to capture photos using a solid-state image sensor instead of traditional film. Once captured, the photos are then stored in a universal digital format that lets you move them to a computer, print them on a printer, view them on a television, e-mail them to friends, or even put them on the Web where anyone in the world can see them. Digital photography is becoming increasingly popular because of the flexibility it gives you when you want to use or distribute an image. It's both the immediacy and flexibility of digital imaging that's made is so popular in so many areas. However, there is one aspect of digital photography that is rarely mentioned. This is the new freedom it gives you to explore photography. In the 1870's when William Henry Jackson was carrying 20 x 24 glass plates around the West on a mule, you can believe he hesitated before he took a photograph. We may not be carrying glass plates, but you and I also hesitate before taking a picture....

Digital Camera Basics

Photographic technology didn't change much for the first hundred years or so. Sure, cameras got smaller and easier to use, lenses grew more powerful, and film quality improved, but folks were still basically taking pictures with a box that focused an image on a light-sensitive piece of film. The world, apparently, was ready for a change. Barely a decade after they first entered the average consumer's consciousness (and price range), digital cameras started outselling film camerasa shift of culture-jarring proportions. By early 2006, a staggering 92 percent of cameras sold were digital cameras. Film photography giants like Kodak, Canon, and Olympus are now major players on the digital market, and they've been joined by manufacturers coming from the electronics side, like Sony, HP, Casio, and Samsung. The makers compete for your dollars by offering dozens of digital camera models with a dizzying array of features. Fortunately, if you understand just a few important digital camera...

How photographs are read

The latter can be a lifetime's study, because so many changing influences are at work. Some aspects of reading meaning from photographs are blindingly obvious, None of us is wholly objective in interpreting photographs - everyone is influenced by their own background. Experience so far of life (and pictures) may make you approach every photograph as a work of art or some form of political statement or a factual record for measurement and research, etc. This kind of tunnel vision, or just general lack of experience, confuses visual communication between photographer and viewer. In a similar way, it is difficult to imagine a colour you have not actually seen or to speak words you have never heard. photomicrographs. A scientist might recognize and look 'through' the picture as if seeing into the microscope eyepiece itself, picking on the subject's factual detail. A sculptor, architect or industrial designer might file it as a reference for particular...

About Stock Photography

This is not a lecture on the history of stock photography, but a few words of explanation may help set the scene for what happened in April 2000 when the first microstock image library was born, signaling the beginning of a revolution in the stock photography industry. Most of the photos you see in books, magazines, and on the Internet were not shot specifically for a particular publication but were selected by picture editors or designers from available photographs that were in stock and ready for purchase. Of course, some images are shot to order. High-end advertising campaigns use photographers working under the direction of advertising agencies. Newspapers need newsworthy images to fill their pages. FIGURE 1.1 We live in a world with an insatiable appetite for images, as this good microstock image helps to illustrate.

Understand how your camera works

No digital photography book can tell you how to turn on your camera, how to adjust the auto-exposure settings, or how to use your model's self-timer to take a picture with you in it (although Wiley Publishing's Digital Field Guide series does offer editions for specific camera models). Those are things best found in your camera's instruction manual. Read it. I promise that the information you seek is in there it may just be hard to find. The instructions for one of my own digital cameras were so cryptic that I found myself creating a cheat sheet with lists of steps, such as, To turn off the auto-sharpening feature, press the Menu button, then. . . . Some of the techniques in this book call for using a specific exposure mode or lens setting. I may ask you to switch to your camera's close-up mode to take photos a few inches from your subject. You may need to use your camera's built-in flash. Learn how to do these now so that you can add some simple but effective tools to your shooting...

What Kinds of Digital Photos are being Taken

People like David Grenewetzki think nothing of strapping their new digital camera to a remote control airplane, or even a rocket, and launching it into the wild blue yonder to capture photos from a bird's-eye view. Until camera prices come way down, you might want to find other applications for your new camera. Fine art photography is a broad category that has included everything from the amazing prints of Ansel Adams to fuzzy prints from a pinhole camera. It's not at all surprising that digital cameras have become part of the hardware repertoire that artists work with. Long before Jerry Uelsmann was making montages, this form of photography was going on. Here is a 1905 image by Adelaide Hanscom that has many of the features we see in manipulated digital art. Photographs don't always have to be put to work. Most are really just for enjoyment. Capturing memories and strange sights are just a few such uses. There is a grand tradition of photographing on the street, capturing the fast...

Getting Familiar With Your Camera

Today's digital cameras are both rich in features and highly capable of helping you get good photos when used in one of many auto modes without requiring you to know much about your camera or photography. However, learning how to use your digital camera and its many features will enable you to get even better photos and do things you never even imagined could be done. In Technique 1, you will first get familiar with your camera. You will then learn how to select important image-quality settings in Technique 2. Technique 3 helps you learn how to select an appropriate shooting mode. Being able to review photos is a significant benefit of digital camera, and Technique 4 shows you how to get the most from the review features on your camera. Technique 5 will help you learn how to change settings quickly so that you don't miss getting the photos you want due to wrong settings.

The Advantages of Digital Photography

Digital photography offers many advantages over film. For one, you can take as many pictures as you want without the burden of buying and processing film. In addition, most digital cameras offer a built-in LCD screen that allows you to view an image right after you've tripped the shutter. How to choose a digital camera These factors alone make digital photography a wonderful tool for better photography. You can fire off a shot, review it on the LCD screen, and decide whether you should try to take the shot again.

Getting a Handle on Digital Camera Choices

Digital cameras have introduced a new wrinkle to the equipment upgrade issue The lure of this attractive new technology causes you to want to go out and buy new gear. But this same technology is changing so quickly that it forces you to face a much faster obsolescence path than you ever witnessed in the past. The first digital cameras on the market offered minimal resolution (640 x 480 640K), rapidly replaced by higher resolution (1068 x 768 1.4 megapixels), replaced by still higher (1600 x 1200 2.1 megapixels), and so on. The current high-end crop of digital cameras hits about 6 megapixels for point-and-shoot cameras and more than 10 megapixels for digital single lens reflex (DSLR) cameras. So digital camera buyers, much like computer buyers, have become conditioned to upgrading their machines every couple of years.

What should I take into account when shopping for a digital camera

Before buying a digital camera you should think about what you intend to use it for. If you are looking for a model for taking snapshots at family gatherings or on holiday, for example, you would be best served by a fully automatic compact or compact zoom camera that takes care of all the details. So, what features should you look for in a digital camera Digital photography is all too often described as digital technology plus some photo technology. However, it is actually photo technology that uses digital technology. Therefore high resolution lenses, efficient flash systems and, if desired, manually adjustable parameters are important in a digital camera. Zoom lenses let you get closer to the subject. Generally, the larger and more powerful the zoom lens, the more expensive and heavier the camera (though digital camera zoom lenses are far more compact and lighter that those on film cameras). For everyday use, a 3x lens is usually sufficient. Where it is too difficult - or too...

Computer in Your Camera

When you get down to it, the biggest difference between film and digital cameras relates to the fact that an image sensor is not an exact replacement for film. Shoot a roll of film and your pictures are saved onto the roll. Expose an image sensor to several different scenes, and all you have are a bunch of electrons, converted by the ADC into digital data. The job of turning that data into an actual photograph is handed off to a very small, but very complex computer within the camera. (See Figure 1-10.) The camera's circuitry and chips, including ASICs and DSPs, process the data to produce form, color, contrast, and luminance and then organize and format it so it can be saved in a recognizable file format. (See Chapter 5 about the file formats, including the RAW format, which postpones much of this processing until the picture is uploaded to your computer.) All this is done according to manufacturer-specific proprietary imaging and color science, which is what really sets each camera...

Whos Taking Digital Photos

Some of the early adopters of high-end digital cameras were photographers doing studio photographs for catalogs and other publications. They were able to quickly adopt these cameras for a variety of reasons. To begin with, objects such as birdhouses or dinner plates don't move. This makes it possible to get the long exposures required by some high-resolution cameras that take three exposures to get a full color image. Another reason is that the images are usually reproduced small enough so their faults don't show. Finally, the production houses that prepare the catalogs prefer to receive digital images so they can avoid the time and cost of scanning them. This studio image was taken with Sound Vision s CMOS-PRO the first CMOS digital camera specifically designed for the graphic arts professional. Image courtesy of Sound Vision Inc. Commercial photographers were amongst the first to adopt digital photography. Using expensive digital backs to large format cameras, these photographers...

Set Up Your Camera for Whats Most Likely to Happen Next

If you miss an important moment because you had to stop and fiddle with your camera, remember that I said this any time you're about to move from one situation to another and don't know exactly what the upcoming shooting conditions will be, set your camera's mode dial to P, which is short for Point and Shoot. That is, the camera does the best to automatically figure out the best compromise between shutter speed and aperture. It also assures you that you're going to get a picture. At the very least, you'll be able to look at that picture after you've shot it and be able to figure out whether you need to be able to go to Aperture or Shutter priority or whether you need to switch to entirely manual control. Speaking of manual control, there's one situation where it's always called forwhen shooting with an external flash that's not made specifically to be controlled by the camera. The best clue as to whether your camera can control the flash is whether the brand name on flash and camera...

Taking Movies with Your Camera

Almost every digital camera nowadays captures video some do it better than others. Cheaper cameras produce movies that are tiny, low-resolution flicks. These mini-movies have their novelty value, and are better than nothing when your intention is to email your newborn baby's first cry to eager relatives across the globe.

Improving Your Photography with a dSLR

A digital SLR has (almost) all the good stuff available in a lesser digital camera, with some significant advantages that enable you to take your photo endeavors to a new, more glorious level of excellence. Certainly, you can take close-ups or sports photos with any good-quality film or digital camera. Low-light photography, travel pictures, or portraits are all within the capabilities of any camera. But digital SLRs let you capture these kinds of images more quickly, more flexibly, and with more creativity at your fingertips. Best of all (at least for Photoshop slaves), a digital SLR can solve problems that previously required working long hours over a hot keyboard. Despite the comparisons you can make to other cameras, a digital SLR isn't just a simple upgrade from a conventional film camera or another type of digital camera. A dSLR is very different from a film SLR, too, even though some vendors offer film and dSLRs that look quite a bit alike and share similar exposure metering,...

Put your pictures in motion by attaching your digicam to the handlebars of your bike

Some people might wonder why the heck anyone would want to attach their digital camera to the handlebars of their bike. Well, in the old days of traditional photography, this didn't make much sense. You couldn't see through the viewfinder while pedaling, so composition was little more than a wild guess. For cycling fans, this means that you can mount your camera on the handlebars, swing the screen upward, and monitor your composition in real time while you're peddling just don't forget to watch the road, please This is a great opportunity for you to share your adventures with those who don't ride with you. If your camera has one of these nifty swiveling monitors, then chances are good that it also has a remote release that you can hold in one hand while riding. Most of these releases not only enable you to trip the shutter, but they also have buttons to let you zoom the lens to different focal lengths. You can literally compose and shoot while on the ride. If you really want to get...

Who Uses Photographs Buying and Selling

Who needs photographs Who uses photographs Who are the clients What are the markets The framework for your future business as a photographer rests on an understanding of the world of photo buyers. Or, if you want to be in the buying end of photography, then knowing what a photographer requires to provide you with the right image is crucial. It will help them solve your visual needs. In this chapter you'll see how the careers of photographer and photo buyer interrelate, and you'll realize the benefits of each understanding the other. Throughout this book we will speak casually of photo buyers. In some areas of photography, photographs are literally bought, and the physical property of a print changes hands obvious examples being family portraits or pictures documenting a wedding. However, in other parts of the profession, such as photography for publication, photographs may be assigned or selected from stock, and certain rights to use those photographs are licensed for use. In that...

Your Pictures Our Passion

If it is bird images you are after, there is no better place to start your search than the RSPB picture library. The extensive collection of pictures includes UK bird species and bird photography from across the world. Every image is clearly displayed and captioned, and the site is bright, colourful and easy to use. On the homepage, there is a helpful 'Themes and Concepts' dropdown menu, which makes browsing straightforward and quick. Users can choose from a list of subjects including In-flight', 'Dawn and Dusk' and 'Cute and Cuddly'. The site also features photographer portfolios, including resident RSPB photographer Andy Hay and AP contributor Danny Green. Images of insects, mammals and plants also feature, so you may even pick up ideas for other areas of your photography. For information on how to submit images to the site, see the 'new photographer submissions' page under the 'About Us' heading. Whether you are browsing or buying, this picture library is a goldmine of images....

Printing and Sharing Your Pictures

Digital technology is just making prints easier for anyone to produce. Instead of stacks of photos of every single picture you've ever taken (plus shoeboxes full of lost negatives), you can have great-looking enlargements of the photos you want to keep, perfectly cropped and carefully corrected in your image editing program. The ability to make prints is one of the best things about digital photography. An alternative to sharing prints is sharing your pictures online through commercial sharing services or your own personal Web space. Such options let friends and colleagues view your photos even if they aren't close by.

Reviewing Your Pictures

Looking at and sharing your just-shot pictures is one of the joys of owning a digital camera. True, the LCD viewfinder is tiny and you won't be able to see much detail, but by golly, you are assured that you got your picture and can instantly show it off. Depending upon how your camera is set up, the last picture you shot may automatically appear on the LCD viewfinder for a few seconds (giving you the option to delete or save it), or you may have to manually switch from camera to playback mode. Usually, the playback symbol on your camera is an arrow icon inside a small box (see Figure 3-5). Press or turn to it, and the camera will display your photos. To page through them, press the left or right arrow of the jog button. While the default setting for playback fills the entire LCD with a single photo, many cameras also allow you to view thumbnails (tinier versions of your pictures), four or nine at a time. You really can't see much of each, but you can see more images at a single...

A trusty walking stick is helpful for fording streams and navigating slippery trails But why not use it to steady your

By attaching your camera to the walking stick, you can create the third leg of what I call the human tripod. You supply your two legs, and the walking stick becomes the third. Simply position your feet about shoulder's width apart, and then lean forward slightly on the walking stick while composing your picture in the camera's viewfinder. You'll find that this method is much easier for stabilizing the camera than trying to hold it with just your two hands. If you'd rather not spend the money on a Leki stick, you can make your own. First, make a quick trip to the hardware store for a 1 4 screw with 20 threads per inch. Get one about an inch or so long. Screw it into the tripod socket on the bottom of your camera. I recommend that you add a plastic washer to serve as a cushion between your camera and the walking stick. Slip the spacer on the screw and position it so that it's flush against the bottom of the camera. With a felt-tip pen, mark the screw right beneath the washer, and then...

Tired of your camera bouncing around during your hike Strap it into place for comfort and for fast access

Here's the hiking photographer's dilemma do you stash your camera in the backpack so that it doesn't bounce around and possibly get damaged, or do you leave it around your neck so that you're ready for the next shot, no matter how uncomfortable it is I can tell you right now that I'm a big fan of finding ways to keep your camera handy. Great outdoor shots present themselves with little warning, and they are usually gone within seconds. Your camera might be safe and sound in your backpack, but it also won't have nearly as many exciting pictures on it. You might miss the shot of a lifetime That said, my gosh, it's aggravating to have a camera swinging every which way as you try to navigate the up-and-down terrain of trail hiking. I've even encountered situations, such as crossing a stream on a log, when my swinging camera just about threw me off balance. Falling in the stream is not good for one's morale, nor is it healthy for the life of your digital camera.

Examining the Parts of a Digital Camera

If you're very new to digital cameras, you might be wondering what all those buttons, LEDs, and windows are for. Here's a quick introduction to the key components of the average non-SLR digital camera. Not every camera will have all these features, and some will have additional features not shown in Figures 1-1 and 1-2. Lens cover This protects the lens when the digital camera is turned off. Picture review Set Execute button Figure 1-2 The back of a typical digital camera. Display control Menu button This controls the amount of information shown in the LCD and produces menus. Some digital cameras have multiple buttons for recording menus, setup menus, and special functions. Print e-mail share photos Some digital cameras allow printing directly from the camera to compatible printers or marking pictures for printing or e-mailing later. Cursor pad Use this to navigate menu choices. Many digital cameras use the cursor buttons to activate frequently accessed features, such as flash...

ADC and Your Digital Cameras Bit Depth

That's what the ADC (analog-to-digital converter) does inside your digital camera (and in fact, the reason why it's even called a digital camera). All digital cameras have an ADC chip inside that converts the picture captured by the image sensor into digital data. Not all ADCs are created equal, however. How well and how quickly it does its job depends upon the manufacturer, chip design, and most importantly, the number of data bits it can process. The ADC works by taking the analog data stream from your camera's image sensor, registering the charge, or number of electrons related to each photoreceptor site, and then deciding whether a piece of data should remain a zero or be a one. These digital pixels consist of data bits that establish exactly what color that pixel will be. The more bits, the more possibilities for more precisely defining the color's hue, saturation, and brightness. Most inexpensive digital cameras process 8-bit pixels. Better digital cameras may have 10 bits or 12...

Defining Yourself and Your Photographs

Making age-old creative decisions in your photography Identifying interesting photography subjects Creating photos that intrigue viewers Turning old family photos into art Transforming your life experiences into digital art J lo doubt about it Photographs are a personal thing. After all, a photo- W graph is a way for you to show the world how you see something After you have those parts of the puzzle knocked out, you have to choose your subject matter. The world that you can catch on your camera is one very big place. From your immediate surroundings to your neighborhood,

Photographs Usage Value

In the end there is only one truth the client determines the value of your photography by its willingness to pay. If you understand that, you understand that the fees for photography are most often determined by the client setting a fee, as in editorial photography, or by the mutual agreement of the parties, as in corporate and advertising photography. In the latter group, the principle of pricing according to what the traffic will bear is the norm. For the good salesperson and negotiator this can present the opportunity to make greater revenues. If you are waiting for the industry to adopt some kind of value formula, please practice your sales and negotiating skills while doing so. Some day you will realize that the formula is never going to exist. Then, if you studied and practiced, you will be ready to engage in the business like a businessperson. Then you can start on the path to making more money by working the business rather than having it work you.

Change Your Camera Position

When you come upon a photo opportunity and raise your camera to shoot, you are not compelled by any state or federal law to remain in that position. Sure, the subject may look good from the first position that you choose to shoot it, but it may look even better from another angle, so why not try it out For the car photograph shown in Figure 3-15, I quickly shot a photo while the street behind the car was empty.

Compact Digital Cameras

Compact digital cameras, also known as point-and-shoot cameras, have become the choice of casual photographers. Compacts are called point-and-shoot cameras because their functions are automatic and they simply require users to compose the scene and press the shutter release. Basic inexpensive point-and-shoot cameras have a fixed focus, which relies on a small aperture and a wide-angle lens to ensure that everything within a certain range of distance from the lens (about 6 feet to infinity) is in acceptable focus. Other point-and-shoot cameras may have a limited focusing range indicated on the camera body. With these, the user guesses the distance to the subject and adjusts the focus accordingly. On some cameras, the focusing range is indicated by graphic symbols (head-and-shoulders two people standing upright one tree mountains). Such lightweight point-and-shoot cameras have a viewing system that is separate from the lens. Generally, the view-finder is a small window above or to one...

Zoom lenses for compact and digital cameras

Compact cameras use both the 135 and APS formats, while digital cameras use focal plane arrays of much smaller formats, typically from 2 3 to 1 4 inch diagonal. Apart from small formats, most of these cameras do not use reflex viewfinders but rely instead on separate optical viewfinders. Both factors influence lens design in that the rear element can be very close to the focal plane, and that a useful zoom range is possible with only a few elements, especially if the maximum aperture is modest, perhaps f 4 at the most. The lens must also telescope down into the camera body for storage, to help keep the size of the camera small. For the 135 format, long range zoom lenses of 38 to 200 mm are used, although the aperture reduces to some f 11 at the long focus setting. The lenses are non-interchangeable and the collapsible telescoping barrel may cause some optical misalignment. Many digital cameras feature a 'digital zoom' feature. This is not an optical zoom using a lens, but by a digital...

First Use of Digital Cameras

Wire service photographers who worked for such agencies as the Associated Press, United Press International, and Reuters and a few larger newspapers were the first main users of digital cameras, starting in the early 1990s. These first digital cameras were bulky, had a slight delay on the shutter release button, and were slow in terms of consecutive bursts, or frames per second. They also suffered by comparison to today's cameras from poor image quality, minimal storage capacity, and poor battery life. They were mostly hybrid cameras that were the result of marrying electronic film bodies to digital backs and self-contained battery packs. Kodak was the leader in producing these cameras and developing the early digital camera technology. These first digital cameras were expensive, with costs almost three to seven times those of current cameras. Of course, at the time, they were the latest technology available, and the industry welcomed them. Another limiting factor in the daily use of...

The Workings of a Digital Camera

The thing is, it took very decent photos. And it did so with few means to adjust exposure or focus and with no opportunity at all to adjust settings we assume should be adjusted with today's cameras. There were no white balance controls, no bracketed shooting or exposure compensation, no depth of field to worry about, no flash or backlighting. You pretty much clicked the shutter and a week later picked up your photos from the drugstore. Today's cameras, with all their automation and intelligence, are very easy to use. But you couldn't blame a novice if the sight of so many knobs and buttons makes him suddenly grow weak. It's not so bad if you take all the controls leisurely and a few at a time. That's what we'll do here to familiarize you with the lay of the land before you embark into the deeper territory of how digital photography works. GETTING TO KNOW DIGITAL CAMERAS Here we're looking at two types of digital cameras. The small one is less expensive, so it doesn't have all the...

Hold Your Camera For Proper Shooting

The Sharper Camera

The proper way to hold your camera to ensure sharp, blur-free images. (Photos Alex Revell) Digital SLR cameras are made to favor the right-handed individual. The basics of properly holding the camera begins with grasping the camera body with the right hand. You will quickly find that most of the important camera controls are within easy reach of your thumb and forefinger. The next step is to create a stable base for your camera to rest on. This is accomplished by placing the camera body on the up-facing palm of your left hand (Figure 1.13). Now you can curl your fingers around the lens barrel to quickly zoom or manually focus the lens. Now that you know where to put your hands, let's talk about what to do with the rest of your body parts. By using the under-hand grip, your elbows will be drawn closer to your body. You should concentrate on pulling them in close to your body to stabilize your shooting position. You should also try to maintain proper upright posture. Leaning forward at...

Digital cameras Introduction

While most film cameras use some form of automation involving digital control systems, they are not called 'digital cameras'. Instead this description is reserved for cameras which use a two-dimensional focal plane array (FPA) of light sensitive elements such as charge coupled devices (CCDs). This array responds to the optical image in an analogue manner to give an electrical output, but this is encoded as digital data giving the location of the element in the array as an (x, y) address, and the value of the response (L). By means of filtered exposures to red, green and blue light, the total (x, y, L) data is recorded for a colour image, then stored in a memory device. The signals may be processed and the data compressed to use less memory, and also used to provide a display of the image. The term digital photography is currently taken to mean use of the full range of image recording, manipulation and display systems to produce images. The range of techniques and equipment used...

Theres much more to digital photography than megapixel brute force And if youre artistically minded you might try your

The great thing about the Jam Cam is that it is wholly unpredictable. One fun way to use it is to bring it along with you when you are shooting with your regular digital camera, take pictures with each camera, and compare the results. Expect strange color shifts, horrible color balance, random pixelation, and some interesting results. I used the Jam Cam to take portraits. Embracing the low resolution, I took the images at 320 240 pixels and printed the 150 KB JPEGs at 11 14. You can also experiment with other ultra-low-rez cameras, the cheaper the better, and see the results you get. Toy digital cameras are a great place to start, as are camera phones or anything with a resolution no higher than 640 480. But resolution is not everything In low-rez mode, your current digital camera might shoot images at only 640 480. However, because of your camera's quality lens, the images won't come out looking quite as funky or interesting as an image from a toy camera. A focus-free plastic lens in...

Normal lenses and digital cameras

One of the factors that determines what is a standard lens is the size of the film or sensor in relation to the focal length of the lens. As most digital cameras have a sensor size that is smaller than a 35 mm frame, normal lenses for these cameras tend to have focal lengths shorter than 50 mm. This is even true for the SLR digital cameras that use the same lenses as the film camera version. To accurately compare the perspective of digital camera lenses, look for values that indicate the lens's '35 mm comparative' focal length. This converts the actual lens size to its equivalent on a 35 mm film camera. Table 15.1 The angle of view of lenses changes when they are attached to digital camera bodies which use a sensor that is smaller than a 35 mm film frame. Camera manufacturers commonly publish Lens Multiplication Factors to help users determine the changed angle of view compared to how it will appear when the lens is used with a film body. This table details the Lens Multiplication...

Dozen Exotic Digital Camera Features

After automobile manufacturers introduced heated seats and Global Positioning System (GPS) for their luxury cars, everyone wanted them, so the designers had to come up with other high-end features, like holographic rear-view mirrors and rocket-powered ejection seats. Digital camera vendors are in a similar race to develop features that are similarly too-cool-for-school. Here are some of my favorite features that are exotic now but probably won't be exotic by the time you purchase your next camera Sound activated self-timers I had a ball playing with a new camera that could be triggered by sound. Just set the audio sensitivity, go get in the picture yourself, and shout, Cheese No more racing to beat the self timer or ending up with a photo showing you holding your camera's infrared (IR) remote control. Image stabilizers Several cameras offer internal stabilization that cancels the effects of shaky hands or the blur induced by the high magnification of telephoto lens. My favorite is the...

Digital Camera Lens Design

To address the potential deficiencies in the light beam, lenses for digital cameras are designed in two ways. First, many manufacturers design their cameras to use only the center portion of the lens. Using the center of the focused light beam forces the portions that are the most divergent from perpendicular to fall in areas away from the image sensor. The second design uses elements that direct the light beam at the sensor surface in a more concentrated and perpendicular manner. These lenses use a device known as a collimator, which is similar to the condenser in a spotlight.

Digital Camera Video and Audio File Formats

As we discuss in Chapter 10, many still digital cameras can also record video and audio. Therefore, you may encounter multimedia file formats in digital photography, such as WAV, AVI, MOV, MPEG, Motion JPEG, and QuickTime. Be sure you understand the nature of the file formatyou are using. For instance, a video format such as AVI is great for showing movies, but doesn't have the resolution for anything larger than baseball-card-sized prints. Also, individual movie frames rarely yield good still image quality.

Few Things To Know And Do Before You Begin Taking Pictures

So you now have a basic grasp of the top ten tips to get you started shooting with your 7D, but there are still a few important details that need mentioning before you can take full advantage of your camera. In this - chapter we'll review some 7D basics on lenses and exposure and get you started formatting your memory card and preparing the camera for use. Let's start with the very first thing you will need before you can run out and take photos a memory card.

Importing from Your Camera

Each folder is usually restricted to holding just 100 images and so a day-long shoot can often end up split across several folders. Even if you have taken less than 100 images, you can still sometimes find that they are split across more than one folder. This is because your camera may have taken, say, 3690 images in all time. If you then take a further 50, the first 10 will fall into one folder and the remaining 40 into another (Fig. 3.4). Aperture's Import From Camera dialog ignores these artificial subdivisions and instead presents you with a single grouping of all of your photos. Aperture is compatible with almost all current digital cameras, so it is unlikely that you will be unable to access your photos in this way, and even if you have trouble now, the chances are that in time your camera will eventually become compatible, as it draws its Raw processing tools from the operating system. Fig. 3.4 Digital cameras maintain a strict filing system, splitting up images into...

In the days of film cameras I seldom recorded exposure settings that would have helped me better analyze my pictures

Every time you click the shutter, your digital camera records valuable picture data that describes the image you just captured. Data such as time, shutter speed, aperture, focal length, and ISO are written to the file header in the Exchangeable Image File (EXIF) format. This information becomes part of the total image file and can be displayed with applications such as Photoshop. In essence, each picture file contains a complete photographic history of the decisive moment, which can be analyzed to help you understand why the image was successful or give you clues as to what went wrong. In this hack, I'll show you how to retrieve this data and use it to hone your photography skills. The EXIF format is an international specification, first established in 1995, that enables digital cameras (and other imaging devices) to write data to the file header of the image. EXIF files use the JPEG DCT format specified in ISO IEC 10918-1. The picture portion of the file can be read by any...

Q Will digital photography make the Zone System obsolete

As of this edition of this book, all of this has changed. Both ink-jet printers and digital cameras have improved to the point that it is now possible to produce exquisite photographic images that are completely satisfying as fine prints. This is why we are now in the midst of what can fairly be called a revolution that rivals the emergence of the roll-film cameras years ago. Photographic film, paper, and chemistry manufacturers who fail to respond to these changes will soon disappear and many photographers find themselves grappling with adapting to a very different set of aesthetic and technical assumptions. On the other hand, it is not a question of digital processes precisely replacing the qualities of fine silver prints. There will always be distinctions that will be important to specialists. Digital processes offer the opportunity to produce work that has extraordinary qualities that, while different from silver-based work, is fully resolved in its own terms. The formal and...

Types of Digital Cameras

System and the large body and lenses, they are far heavier than compact cameras and therefore often a difficult choice for SFAP. Between these main camera types, several other designs exist. The so-called bridge cameras with their large zoom ranges have an appearance and manual exposure control possibilities similar to DSLRs, but non-interchangeable lenses and the smaller sensors of compact cameras. The last few years have seen a new type of mirror-free system camera, the so-called Micro Four Thirds standard, with similarly sized sensors as DSLRs but smaller interchangeable lenses and lower weight, which makes them an interesting camera type for SFAP applications. At the high-price and high-quality end, there are also a few digital cameras of the classic rangefinder type (compact design, manual focusing mechanism, fixed single-focus lens) that was best known for analog cameras in the mid-twentieth century. Still a drawback for many digital cameras, especially compact models, is the...

Let It Rain in Your Photos but Not on Your Camera

Rain can put a damper on one's day, but it can also offer many great photo opportunities. As long as your camera and lens stay dry, you will probably soon discover why images of your pets and other loved ones taken in the rain (or just after it rains) can be so rewarding. A resealable plastic bag can help keep your camera dry (just cut a hole for the lens), and if you are so lucky, a large umbrella held over you and your gear by a friend or family member can make a huge difference. Some go as far as using an underwater housing device to keep their gear dry w3.5 . A soft, clean cloth for your lens, or even better, a package of photo wipes such as Pec-Pads w3.6 , stored in a small plastic bag can be invaluable for keeping your lenses clean and dry.

Use albums to divide and conquer your photo library

Albums are by far EasyShare's most useful organizational tool. To create a photo library where you'll be able to find photos in the distant future, create albums with descriptive names, like Aunt Elsie's 92nd Birthday, or Oregon Vacation 2006. And, as if you haven't heard it enough already, never hesitate to drag photos into multiple albums.

Why Film and Digital Cameras See Colors Differently

For photographers, one area of digital photography that is uniquely different from film is how color temperature is controlled. In conventional photography, color adjustment is accomplished using either color-correction filters or color-balanced film. With the exception of professional films, all films sold are balanced for daylight. The film boxes shown here display two different ways (daylight and outdoor) to indicate film that is color balanced for daylight. Daylight-balanced film is so common that many film boxes no longer indicate that the film is color balanced for daylight. For the digital photographer, color temperature correction is accomplished by the camera. Called white balance (WB), it is a new concept for most conventional photographers, although videographers have always worked with it. Without getting too technical, WB controls what a digital camera perceives as a neutral color. Without WB correction, white objects tend to

The genius of digital photography

The genius of digital photography is immediacy. The old days of waiting for your film to be developed and returned from the lab are gone. You know if you got the shot as soon as it appears on your camera's LCD monitor. You also never have to pay for film again. Ever. But for the most part, people have made the switch to digital because they can capture their images on cards the size of a postage stamp, they don't want to worry about film expiration dates, and so on. But with these advantages is also a curse. If you're not careful, the very genius of digital photography can turn you into a bad photographer. You don't pay for film so you tend to shoot more images. This is a good thing if you take good photographs. But if you just shoot everything that pops up in front of your camera, you're going to get a lot of bad photos that end up in the trash bin. To take advantage of the genius of digital photography, be in the moment and do your best to make every image a keeper. If you apply the...

Tip Grow as a Photographer with Your Camera

While -stops and shutter speeds might seem confusing at first, they are among the most important concepts behind good photography. If you want to learn how to take control over the creative possibilities of good exposure control, take your camera off auto and experiment. Shoot the same picture using different combinations of -stops and shutter speeds, then, when you look at the photos on your computer, check out the metadata (see Chapter 5) to see what settings captured which photo. You'll be amazed how quickly you'll be comfortable and having fun with it all.

Connecting Your Camera to a Telescope

Folks with 35mm SLR cameras can easily connect their camera to a telescope to take extreme-telephoto pictures or even photograph the heavens. If you want to try that with a digital camera, you're in luck a company called LensPlus (www.lensadapter.com) sells a little gadget called the LE-Adapter which acts as a docking port between your digital camera or camcorder and other optical gadgets like telescopes, binoculars, spotting scopes, and microscopes. It works with a wide variety of digital cameras all you need is a set of threads on the front of your camera's lens to screw on the LE-Adapter. The adapter comes ready to screw onto cameras with either 37mm or 52mm diameter threads. If your camera has a different diameter lens, you can buy a step ring that goes from your camera's threads (the size is usually inscribed right on the front of the lens) to either 37mm or 52mm.

Hints on Web Sharing Your Digital Photos Successfully

One of the great benefits of digital photography is the ability to share photos quickly and free on the web.The two main methods for doing this are by e-mail or on a photo-hosting website such as ACD SendPix, and both of these can be done right from ACDSee. The hints below are general guidelines to follow to have the most success in sharing digital photos on the web.

Taking Your Photography To The Next Level

The Creative zone is the name given by Canon to the shooting modes that offer you the greatest amount of control over your photography. To anyone who has been involved with photography for any period of time, these modes are known as the backbones of photography. They allow you to influence two of the most important factors in taking great photographs aperture and shutter speed. To access these modes, you simply turn the Mode dial to the Creative mode of your choice and begin shooting. But wouldn't it be nice to know exactly what those modes control and how to make them do our bidding Well, if you really want to take that next step in controlling your photography, it is essential that you understand not only how to control these modes, but why you are controlling them. So let's move that Mode dial to the first of our Creative modes Program mode.

Helping Your Camera Cut Through Darkness

Whether you're shooting with a film or digital camera, taking pictures in dim lighting poses special challenges. After all, a camera works by recording the amount of light in a scene. If the camera's eye doesn't sense much light well, you see the problem. When adding light either isn't possible or doesn't solve your exposure problem, you can help your digital camera cut through the darkness in the following ways If you are working in autoexposure mode, you may also be able to tweak exposure by increasing your camera's EV (exposure value) compensation setting, if available. Your camera will then adjust aperture or shutter speed or both to produce an exposure that's brighter than what the camera's autoexposure metersuggests is correct. (Some cameras also raise ISO automatically) Check out Chapter 2 and Pages 9 and 17 of the color insert for more information about EV compensation. As I mentioned in the introduction to this chapter, the image sensors on most digital cameras have a light...

Pixels Building blocks of digital photos

Every digital photograph is born with a set number of pixels, which you control by using the capture settings on your digital camera. (See Chapter 3 for details.) Most cameras sold today can record at least 6 million pixels, and higher-end models can capture 10 megapixels or more and some pro models can capture as many as 15 or 20

How to Read Your Digital Camera Manual

Most digital camera users I meet have never read the user manual that comes with their camera, and there's a good reason why they don't. The manual that comes with a digital camera is usually Figure 7-1 Digital camera user Figure 7-1 Digital camera user facts. On the other hand, some camera manuals are written with beginners in mind. An example of this is found in Figure 7-2, which is from a manual for a late model digital camera made by Kodak. Regardless of how good or bad the manual for your camera is, you need to spend some time reading it and learning how the camera works.

Using Your Cameras Color Controls

They photograph exactly what they see. In the case of the rose in the dark room, the camera would probably capture something close to black, with varying levels of maroon. Just how much black or dark red is captured will depend upon that particular digital camera's ability to distinguish details in shadows. To make up for their lack of human intelligence, digital cameras have complex internal programming (algorithms), plus a variety of powerful interactive tools and features, to fine-tune the way they capture color. In this chapter, you'll learn how to distinguish the color and quality of light and how to use your digital camera to capture the best and most pleasing colors. For further information about color management getting the colors you expect when you show or print your photos please turn to Chapter 20.

Sensible Approach to Learning About Your Camera

If you attempt to learn all of the buttons, dials, and menu controls in a single sitting, you will probably forget about more than half of them by the time you use your camera. Most humans learn best by physical association. To learn the locations and uses of your camera's features, try the following approach Figure 7-6 You won't master your camera unless you apply what you learn with the camera in your hand. Figure 7-6 You won't master your camera unless you apply what you learn with the camera in your hand. After you understand the basics of your camera, you'll probably find that many more advanced features still need to be figured out. The best way to master these features is to learn about them as you need them. For example, if your camera has a noise reduction feature, you don't really need to learn about it until you begin working on low-light or night photography.

Setting up your camera

In the studio, it's fairly easy to set up your camera on a tripod or other support and not have to worry about it shifting. On location, you might need to make sure that the ground underneath your tripod is firm and solid. Put a rock under one or more legs, if necessary. If you're shooting on a slope, you might want to lengthen one or more legs of the tripod and shorten others.

Choosing When and How to Use Your Cameras White Balance Settings

In the early days of digital photography (way back in the early 1990s), we could easily recognize which digital camera had taken which photo by its signature color frequently a color cast consisting of some shade of blue. Thank goodness Photoshop had already been invented. We'd bring the pictures into that imaging program and, before doing anything else, remove the color shift. Then, we could edit the photos and use them. Digital cameras have come a long way since then. Just about all the major models and many of the minor ones do a good to excellent job with white balance. While in most cases, the average user will be quite happy with the pictures she gets with her camera's default white balance settings, understanding and trying the various white balance options can lead to even better pictures, especially in difficult lighting situations.

Managing Digital Camera Color

Color management for digital photography starts with the original capture. You'll want to make sure you are using the best camera settings to ensure the most accurate color and best image quality. There are several methods you can use to manage the color of your digital captures. They range from simple camera settings, to custom white balance settings, custom camera profiles, and exercising control with RAW capture. Each option has its own benefits and compromises in terms of convenience, color accuracy, and flexibility.

Twenty Tips and Tricks to on Microstocks

The idea when submitting to microstocks is to make money, so your goal should be to formulate a plan that maximizes your prospects of success. What is in that plan will depend upon the kind of person you are and how much time you want to spend on stock photography. So far, we have covered quite a lot of ground. It is a good time to take stock (no pun intended), to think about what we have learned, and to add in to the mix a few tips that I think will enhance your prospects of making money from microstock photography. Some tips work better for one type of photographer than another, but let's start with a tip that I think applies generally to everyone.

Learn to Decipher Your Camera Icons

There isn't enough room on the body of your camera to write out the entire names of button and dial labels, so icons are used to indicate the camera status and to label controls. When you are learning how to use the features of your camera, get familiar with the icons associated with each feature or mode this way, when you're wondering why the camera isn't working as expected, you can look at the LCD status screen like the one shown in Figure 7-11 (not the LCD viewing screen) and see what features are turned on or turned off.

Spectral sensitivity of digital cameras

The fundamental spectral sensitivity of charge coupled device (CCD) sensors used in digital cameras is that of the silicon itself, modified by interference effects within thin overlying layers forming part of the chip construction. The spectral sensitivity of a typical monochrome CCD is shown in Figure 13.7, from which it will be seen that there is rather a low blue sensitivity but considerable sensitivity extending into the infrared region. In most CCD cameras the infrared sensitivity is restricted by an infrared absorbing filter on the face of the CCD, but in special purpose cameras a separate filter may be fitted to the camera lens.

Discover Shortcuts for Your Camera Settings

Some digital cameras have shortcuts included to help you quickly change settings. For example, on my Nikon, if I press two particular buttons at the same time, the camera will prepare to format the memory card without my having to open the menu and select the option there. Most of these shortcuts involve pressing buttons in combination, and they can be real time-savers. Discussions of most of the shortcuts are cleverly hidden in the manual. As you find and learn each feature of your camera, make a note of any feature shortcuts. Other shortcuts in your camera may be accessed via programmable buttons or dials. On professional digital cameras, many features are used only in certain photographic situations, such as changing the sensor size. For a photographer who needs a particular set of features to be handy, buttons and dials can be programmed so that you can quickly change the settings that they are programmed to control. Programming a dial or button sounds complicated, but it isn't....

Using Your Cameras Other Color Controls

The purpose of white balance tools is to remove any color shifts from your pictures, so that the true colors of the scene can be better captured. (Or, conversely, you can use white balance settings to introduce a creative color shift.) Other digital camera color tools are more involved in defining and refining your photo's underlying colors. Many people will happily use digital cameras for years without ever dealing with color models, color modes, contrast, or saturation. Then again, many people live their lives happily eating out only at McDonald's. But once they find out about the added culinary dimensions of seafood, steak, and even Thai or Greek restaurants, dining out becomes so much more interesting and rewarding. So it is with learning to experiment with photographic colors. Not only will it give you a greater variety of options to spice up your photography, but you may also find that one special setting that fits your personality, needs, and artistic preferences.

Installing and Using Flickr Uploadr

If you want to upload dozens of photos at a time, then you probably feel constrained by the upload form's limit of six photos. In that case, Uploadr is the tool for you. With Uploadr you can send many photos at a time to Flickr using Windows XP and a handy drag-and-drop tool. To install Uploadr, go to www.flickr.com tools , and then download the Windows XP installer program. You need to make two decisions during the installation whether to place a shortcut to the program on your desktop and whether to add a Send to Flickr command to your right-click menu. The shortcut question is simply a matter of tasteyour desktop may already be too cluttered with shortcut icons. The right-click menu, though, is a real timesaver. Leave this option turned on, and you can send any photo to Flickr just by clicking on it. With Uploadr installed, you have two great ways to send photos to your Flickr online library Send photos with Windows' right-click menu . Right-click a photo file and choose Send to...

Online Digital Camera Forums

Before you buy a camera, you should do a little research to find the unit that offers the best features for you. Online digital camera forums are a great resource to learn about what a particular digital camera can and cannot do. I highly recommend Phil Askey's excellent web site, Digital Photography Review (http www.dpreview.com). In addition to detailed reviews and news, Phil's site offers online forums that are manufacturer-specific. If you apply yourself and make the effort to learn everything you can about your camera, you'll find that your photography improves following this advice is better than just buying any accessory you can find. Make the investment of time to learn the ins and outs of your camera, and you will be rewarded for the effort.

Emailing Photos to Flickr

As if the Web form, Uploadr tool, and right-click menu command weren't enough, Flickr lets you email photos to your library, too. To get your special Flickr email address, go to www.flickr.com tools , and then click the Upload by email link at upper-right. The odd-looking email address you see on the next screen is your dedicated address for uploading photos by email. (It probably consists of a combination of words and numbers and ends in photos.flickr.com .) On the left side of the Uploading by email page is a link that reads, We can also send you an email to add this address to your address book Unless you relish the idea of memorizing your cryptic upload address, click this link. When Flickr's email arrives, add the sender to your address book. In Outlook, for example, right-click the Sender's address and choose Add to Contacts from the shortcut menu. From then on, you can upload photos simply by typing Flickr in the To field of a new email message. Enter a title for your photos in...

Careers In Stock Photography

If you haven't had experience with stock photography, it's important to be familiar with the opportunities available to you and the realities of that part of the business. In many ways stock photography is a microcosm of the larger world of photography. Many of the same career possibilities available in the wider world of photography exist in stock. There are photographers who shoot specifically for stock, and others who make stock an adjunct to their assignment careers. A few of the larger stock agencies actually have photographers on staff.

Organizing Photos with Flickr

You've uploaded your photos to Flickr and now its time to get organized. On your Flickr home page (www.flickr.com ), you see a few of your photos and others under the heading Everyone's photos. In the upper-left corner are some links to other pages Home . Flickr's home page is a no-nonsense, bare bones screen with big, clear links to the pages where the real business takes place uploading photos, and viewing photos (yours or everyone else's). When Flickr has any news or announcements to tell you about, you'll read it here first. Tags . In Flickr, these keywords or phrases are your primary tool for both organizing and searching for photos. But they're much more than that. In Flickr's lively online community, tags are a basic unit of currency. Most members add several tags to each photo they upload, hoping to see and be seen by folks all over the world with similar interests. On the Tags page, Flickr displays current lists of the most popular tags for the past 24 hours, past week, and...

Backing Up Your Photo Library

If you ever see a photographer running from a burning building, chances are her arms are full of photos. After all, most photos are literally irreplaceable it's impossible to go back to that place and time and capture that image. One of the dangers of digital photography is that your shots are vulnerable to accidental deletion, hard drive crashes, and other electronic snafus. But every cloud has a silver lining and in this case it's that digital pictures are very easy to copy. You can make unlimited copies, in fact, and each one's a picture-perfect, exact duplicate of the original. There's no excuse for not having a foolproof backup plan and following it faithfully. That's what this chapter is all about.

How Is Stock Photography Marketed

There are a number of ways to market stock photography through a stock photo agency, through a portal agency, or through your own Web site. While some photographers market their own work to stock buyers, using Web sites for the purpose (though in the explosion on the Internet individual Web sites are in danger of getting lost in the shuffle), others leave that aspect of the business to one or more of the many stock photo agencies in the United States and abroad. In addition to handling archiving, billing, and licensing of reproduction rights to clients for a percentage of the reproduction fee, many agencies spend time and money researching and opening new markets for the use of stock photography with capabilities way beyond the average individual. In the United States, the Picture Agency Council of America (PACA) is a trade association that represents the interests of member photo agencies (www.pacaoffice.org). This is a good starting place if you hope to find an agency to represent...

Night and Time Exposures with a Digital Camera

Most digital cameras can take dramatic low-light exposures. Done properly, dark or moonlit scenes may miraculously appear lighter, displaying details that look pitch blackto your eyes. Taking slow or time exposures to capture photos in low light requires a number of steps Autofocus may not work in low light. You'll have to either use manual focus or set the camera to a program mode, such as night mode, if your camera has it. (See Chapter 7.) Depending upon your camera, your slowest shutter speed may be 15 seconds, 30 seconds, or 1 minute. (A few cameras have a bulb setting, which means the shutter remains open as long as you hold the button down. But for technical reasons, the longest bulb we've seen in digital cameras goes only 2 minutes.) If you don't have adequate light when your shutter speed is at its slowest (the camera will warn you with a beep or a status light if you are underexposed), you can either select a lower -stop to admit more light or boost the ISO equivalency, or...

Trigger Your Camera Remotely

There are also many times when it would be convenient to control your camera without having to be behind the lens. Cable releases have been a staple for a long time, but the distance you can venture from the camera limits you. PocketWizard Radio Triggers can act as a wireless cable release to fire both camera and Aash. Just slide a PocketWizard Radio Transceiver on your camera hot shoe and connect it to your camera with a remote Trigger Release Cable. With a second unit in your hand, match the channels on each PocketWizard Radio and press the Test button. The transceiver on the camera will fire the camera from your remote command. Should you wish to operate your camera in an automatic mode, auto-focus and metering work just as if you were pressing the shutter. Not being tethered to the camera frees you to either better interact with your subject or, in the case of wildlife, to remain at a safe distance.

Your Next Digital Camera Night Sky Photos As Litmus Test

But in the still-emerging field of digital photography, what you need in a digital camera to get pristine night sky photos is not as straightforward. Read on to shed some light on the subject and find out how the requirements of night sky digital photos can also be used as an excellent indicator of how satisfied you'll be with your next digital camera as a whole.

Your Digital Cameras BuiltIn Flash

The vast majority of digital cameras have a built-in flash. Also called a strobe or strobelight, it works by flashing (strobing) very briefly but brilliantly when a high-intensity electrical charge passes through a tube filled with inert Xenon gas. Unlike a conventional flashbulb, which burns up the wire filament in a single burst of brilliance, the gas-filled strobe can flash many thousands of times. Usually positioned next to the built-in flash is a tiny sensor that measures the light bounced back from the subject. (Some cameras have an internal sensor.) When it decides that there's just enough illumination for proper exposure, it will instantly turn the flash off. Depending upon the make and model, some digital cameras come equipped with certain refinements, such as variable flash intensity (flash compensation), a popup flash rather than one in a fixed position near the lens (higher is usually better, for reducing red eye), and a couple neat technical tricks, like front or rear...

Advantages of Digital Cameras

Digital cameras offer you many advantages in portrait photography. Most important of all is the chance for the photographer to review the pose before the subjects leave. Because you can spot problems before your victims skedaddle, you have a chance to correct them while everyone's still there. Another huge advantage of the digital camera is that it gives you a chance to make sales while your customers are still excited from their sitting and still in high spirits after all that positive feedback you've been giving them. (You have been giving them positive feedback, haven't you ) Learn to use your digital camera's review feature to its best effect. Here's a list of some of the things you should analyze as you play back your shot Make sure that the photo is properly focused. Although you can't be dead sure while reading your camera's LCD screen, you can at least eliminate really poor shots. If you have a digital camera that can be hooked up to a television to play back images, by all...

Recording Video and Audio with Your Digital Camera

The heart of every digital camera is its image sensor. Among the many arcane characteristics and specifications buried in white papers and technical descriptions of photosensitive sensors is the fact that charge-coupled devices (CCDs) and complementary metal-oxide semiconductors (CMOS) capture image data at the rate of 60 frames each and every second. If the camera receives no instruction to capture a picture (which happens only when you press the shutter release), most of those 60 frames per second (fps) are simply thrown away (though some get diverted to the LCD viewfinder so you can preview what you might shoot). Actually, many digital cameras allow you to do just that. It's called video. Better yet, many digital cameras also allow you to record audio that synchronizes with the video in other words, movies just like a DV camcorder. For most users and situations, your still digital camera is capable of capturing usable movie clips that are good enough for displaying over the Web and...

How Your Digital Camera Differs from Your Camcorder

Superficially, digital cameras and digital video (DV) camcorders are kissing cousins. (See Figure 10-1.) They both have many similar or identical components and features. Both may be capable of recording still images, videos, movies (video with sound), and audio clips. Depending upon the model, both may save to some form of digital tape, a mini-CD or DVD disc, or standard memory cards. Where they part company is how and how well they capture, record, and store the images, video, and audio data. Figure 10-1 Digital video camcorders and still digital cameras are kissing cousins, but they are definitely different creatures. Note the ergonomics that force you to hold and shoot each one differently. (A) A Sony DCR-H20 MiniDV camcorder with an articulated (swing out) LCD viewfinder. (B) A Sony DSC-V1 still digital Figure 10-1 Digital video camcorders and still digital cameras are kissing cousins, but they are definitely different creatures. Note the ergonomics that force you to hold and...

How do I connect my digital camera to my computer system and download images

Generally, assuming the relevant software drivers for the operating system used are available, and as long as the camera's interface is identical to that of the computer, it is easy to connect your camera to your computer. The main connection type is USB which can be divided into two main versions USB 1.1 and USB 2.0. USB 2.0 comes in three different speeds Hi-Speed (480 MBit s), Full-Speed (12 MBit s) and Low-Speed (1.5 MBit s). Most cameras use the USB 2.0 Full Speed.

Its strange to think that there are different definitions ofwhite since your brain normally compensates for the

Camera's pre-existing settings to tell it what sort of light you're shooting in. There's usually a choice of at least five. For indoor shots, there's tungsten (in other words, standard incandescent room lighting), fluorescent lighting or flash. If you're outdoors, there'll be two or three choices - often sunny, cloudy or overcast. Some digital cameras will allow you to set the white balance even in fully automatic mode others need you to be in a semi-manual or manual mode such as aperture priority. Once you're in the right mode, just select the appropriate one and that's it. The only thing to remember is to reset it (or set it back to automatic) if the conditions change. Of course, there are times when you might want colours that are different to the real ones - you might want more warmth. Don't worry the joy of digital photography is that all those things can be achieved later on when you transfer the pictures to your PC. It's almost always best to start with a faithful reproduction...

Choosing Your Digital Camera According to Its Video Capability

If video is a vital feature to you, then you should carefully examine the specs of any still digital camera before you buy. They vary considerably. Here's what you should look for Resolution Remember the resolution or size images that your still digital camera captures is going to be much higher than its video capability. So, be sure to pay attention to the specifications for video resolution, too. Many digital cameras offer 320 x 240 pixel video resolution, which is a good all-around size for the Web and emails. Some still digital camera models allow users to select between or among different resolutions. Frame rate How many frames, or pictures, per second (fps) a still digital camera can take is important. Many digital cameras allow you to record video until you run out of storage space. Others have more limited buffers or slower electronic components and eventually must discontinue recording. Of course, there's a direct relationship between resolution, frame rate, and recording...

With a series of photographs of the same subject in hand you can judge which shot is sharper without ever opening a file

You can make solid judgments about image sharpness without ever opening the file. Both Windows and Macintosh computers provide you with all the information you need by simply opening the folder that contains your pictures and viewing some of their basic data. Eyeballing sharpness is all a matter of size file size, that is. The larger the file, the sharper the picture. When you're shooting in JPEG mode with your digital camera (which you usually are, unless you explicitly switch to TIFF or RAW), the files are compressed in the camera so that they don't take up too much room on your memory card. Fine, sharp detail is harder to compress than softer, duller images. So, the resulting file for a slightly sharper image will be a little bigger.

Usb 20 Card Reader For Transferring Video To Your Camera

Unlike DV camcorders, no current consumer digital camera comes equipped with a high-speed FireWire interface. So, unless your camera has USB 2.0 which at its fastest still will be time-consuming don't even think about transferring video data directly from your camera to the computer.

Protecting Your Photography

When your photography goes on the Web, it's there for anyone to take and use. Legally, they must first have permission from you as the copyright owner to use it. However, there are people who are ignorant of copyright law or just ignore it. As you show more and better photography, your concern increases. A few words are in order, at least to educate newer photo users. Here are some things to try

Using Black and White for Weather Photographs

It makes no sense these days to take a picture in black and white when you're out in the field. Why would you want your camera to make decisions on the gray tones when you can do it with a number of image processing programs Shoot in Raw, and you've got sliders that let you adjust a number of parameters for your black-and-white images. Remember, too, if you didn't shoot in color, you won't have color anymore.

Digital Camera Choices

The digital camera I used for the examples in this chapter is the Nikon D70, one of the first DSLRs to provide both professional-level features and quality at a consumer-oriented price. There are many other digital cameras that fall into this category, most notably the Canon EOS 20D but, once again, all of the principles I cite apply in very similar ways to cameras in this price and feature range. In general, point-and-shoot type cameras aren't capable of producing images that will work with these techniques.

Dont Worry About Looking Perfect Take Pictures of Real Life

I saved this tip for last in this chapter because it fits in well with 85 the idea of photographing our pets and people friends when relaxing or sleeping. We're often conditioned to get set up and made up when we know people are going to take our pictures. In fact, many people don't even think of taking pictures unless they go on vacation or have a party or family gathering. Instead, consider taking photos of your loved ones on a Sunday morning in their pajamas just after they've brushed their teeth and grabbed (or fetched) the weekend paper, or late at night while watching a movie, or in the yard covered with dirt. Most pets seem to always be ready for their close-up, but they rely on us to grab the camera If the moments are special to you, then those are the times you should be taking pictures.

A great way to share your pictures is to post them on the Web Heres an easy way for photographers to leverage the

Creating a web site is a cumbersome task, even for people with quite a bit of web design experience. So, what if you just want to get some images up for friends, family, or a client to review and comment on This hack will get you on your way quickly, using a built-in feature of Adobe Photoshop.

Using your cameras LCD review feature

1 Sharpness LCD screens aren't necessarily an accurate way to judge image sharpness. However, some cameras offer the ability to magnify a portion of your image, which can help you see whether your camera's autofocus or your manual focusing is close. If not, you can switch autofocus modes (some cameras let you choose which area of the 1 Exposure Your camera's LCD screen can help you determine whether your exposure is on target. Some cameras let you call up a histogram, which is a kind of scale that shows the distribution of brightness values throughout the image. The histogram can help you judge your exposure. If your exposure isn't spot on, you can make changes immediately so that subsequent action shots are better. Sports photography usually calls for such high shutter speeds to stop action that no photographer would use a tripod to prevent blurry photos from camera shake, unless working with a high-end digital camera with a huge telephoto lens (which isn't something the average...

Using Your Camera as a Voice Recorder

Some still digital cameras allow users to record sound as WAV files. This feature is almost always accessed through the menu options, and records sound in place of images. Once this feature has been selected, you start recording by pressing the shutter button and end it the same way. How long you can record depends upon the memory card. For instance, a 16MB memory card can record hours of uninterrupted audio, and a 256MB card can get 17-18 hours. Since the image sensor is turned off, the batteries should last much longer than usual. How good is your recording About the same audio quality as an inexpensive 8-bit digital tape recorder. We confess that we've used a digital camera to tape interviews when we forgot to take along a digital recorder, or when the digital recorder we had wasn't equipped with removable memory or a USB port to transfer WAV files to the computer. (Audio is easier to edit, store, and transcribe in the computer than constantly pushing stop-and-go buttons on a...

Dealing with latency of your camera

Latency is the time required to write the image you've just taken to your storage media. When you take a picture with a film camera, the shutter releases, and the image is immediately registered on the film at the speed of light, so to speak. When you take a picture with a digital camera, the image has to be captured and then recorded onto your memory card. The image capture and storage process can take a second or two or even longer. How long the process takes and whether your camera will continue taking additional photos while writing to the card are important questions. Digital cameras use buffers (built-in memory) to temporarily let you keep shooting while the buffer contents write to removable memory. If you keep shooting, eventually the buffer fills, and you have to stop until it has made enough room for you to resume shooting. Other cameras might not be able to use their buffers quickly enough for their highest resolution files but will let you keep shooting if you choose a...

Music from Your Digital Camera

If your still digital camera has a built-in speaker (most do), you probably can play music through it. All you have to do is record some tunes on the memory card, either on your computer or any handy MP3 device, slip it into your camera, and put it in playback mode. Most cameras recognize and play WAV files that were recorded elsewhere. The sound quality may not be great, but hey You have a handy music box built into your camera.

Bring Your Camera along for a Swim

Cameras can't swim they'll break in the water. Fortunately there are cameras that are watertight so you can take them into a pool or an ocean without any problems. Dirt, rain, and mud can't harm these cameras either, so they're perfect for any outdoor adventure. If you don't want to spend a lot of money on this kind of camera, you can find disposable waterproof cameras at drug stores or photo shops. These cameras use film, which needs to be developed, but they're much less expensive than waterproof digital cameras. As the name disposable implies, you can only use these cameras until the film is all used up. A A Taking pictures with a waterproof, one-time use film camera can be a lot of fun and you can get really creative.

Digital Photography Tips and Tricks

Learning digital photography can be a fun adventure. When you have the time to explore, that's exactly what you should do, trying unknown commands and features without quite knowing what the results will be. But when you need to get a particular photograph or reach a specific project goal, you'll need to know what shortcuts will work quickly and efficiently. In this chapter, we'll share some of the shortcuts we've learned over the years from experience and from talking with other photographers. These tips and tricks will get you where you need to go with your camera faster, easier, and with better results, while still having fun with the photography. Most importantly, some of them may help you get the shots that otherwise might have gotten away.

Keeping Your Camera Steady

No photo will look sharply focused if the camera moved while you were taking the shot. Unless you are shooting at a fast shutter speed (see Chapter 6), you will want to find ways to steady your camera. Here are some ideas that may help you achieve maximum stability If your digital camera has some sort of anti-shake or image stabilization technology (a few models with large zoom lenses do), then by all means turn it on that is, unless you are using a tripod, in which case anti-shake technology is entirely unnecessary. If you don't happen to have a tripod handy, look for a desk, rail, table, windowsill, or some other nearby solid object on which you can place or brace your camera while shooting. Often, the most important thing to help ensure that your camera is steady is knowing how to hold it correctly. Because there are so many different sizes and form factors (that's the industry buzzword that means shapes), we can't give you specific advice on the best way to hold and handle your...

Use Your Camera as a Journal

In many places that you photograph, either on vacation or just while shooting photos for fun, you can use your camera as a Figure 10-9 Signs like this provide a wealth of information and are easy to record with your digital camera. Figure 10-9 Signs like this provide a wealth of information and are easy to record with your digital camera. With a film camera, it's difficult to justify taking these shots, since developing these photos can be expensive and they're usually not as interesting to look at as more creative shots. But with a digital camera, you can capture a lot of information about a subject by taking a single photo, like the one shown in Figure 10-9. This helps you remember where you've been and the importance of an area where you shot. While taking such photos, it is useful to set the quality setting of your camera lower. This gives you more images per card and doesn't waste storage space on an image that will never get printed. Another valuable use of your digital camera...
