The Digital SLR Difference

Discovering why digital SLRs are the next big thing Finding out how your shoot will change big time Exploring dSLR advantages Looking at downsides What downsides 7oday, the digital SLR (or dSLR) has become such a hot item among people who take pictures that virtually everyone, including your grandmother, probably knows that SLR stands for single lens reflex. However, your Nana or you for that matter might not know precisely what single lens reflex means. It's a camera (film or digital) that...

Salvaging images from RAW files

Your image-editing skills will improve, and with an image saved in RAW format, you can salvage images that weren't usable before you gained new capabilities. Pictures that you didn't think you had any use for might turn out to be worthwhile with the passage of time. For example, take the photo shown in Figure 8-5, which I originally used in Chapter 6 as an example of how you can take photos in dim light without a tripod if you have a lens with a large maximum aperture. It's true that the...

Testing for tremors

Before looking at the latest technological cure for shaky hands, try this exercise to see just how bad you have the affliction 1. Find a scene that contains sharp pinpoints of light, preferably at night so you'll have a dark background, such as a scene with streetlights. 2. Switch your camera to Manual mode so you'll be able to vary both the shutter speed and f-stop independently. 3. Take several pictures at a fixed f-stop but vary the shutter speed for each picture. Use various shutter speeds...

DSLR Next Great Digital Camera

If you've already made the jump to a digital SLR, you've discovered that the dSLR lets you take pictures the way they were meant to be taken. After using other film or digital cameras, anyone interested in taking professional-looking photos notices why dSLRs stand out You can view a big, bright image that represents (almost) exactly what you'll see in the final picture. No peering through a tiny window at a miniature version of your subject. No squinting to compose your image on an LCD...

Matching pixels to print sizes and printers

If nice-looking prints are important to you, you need to pay as much attention to your printer as the number of pixels in your digital SLR. In truth, printers with lower resolution don't benefit much from digital shots with high megapixel counts. They might produce worse results because they're forced to discard lots of that precious detail to squeeze the picture information into their available output pixels. You need a printer with lots of resolution to do the best job with a high-resolution...

Touring Through a Digital SLR

Film Camera Components

Now is the time to explore the innards of your digital SLR as a way to better understand how to use all the nifty features your digital shooter includes. At best, these sections give you a better handle on why, sometimes, the results you get when you press the shutter release aren't exactly what you expected. At worst, you can find more convincing excuses to give when you goof. In some ways, the basics of a dSLR have a lot in common with the conventional film SLR, or indeed, any film camera....

A fast tens or not

As you discover in Chapter 6, a lens with a large maximum aperture (generally, anything faster than f2.8) is a must only if you're hand-holding (that is, shooting without a tripod) your night photos or, perhaps if you want to shoot with flash and need your speedlight's illumination to reach as far as possible. An f2 or f1.4 lens might let you take some night pictures at > 30 of a second hand-held or, with image stabilization (which I discuss in the next section), at slightly slower shutter...

That syncing feeling Coordinating flash and shutter

Many new SLR owners become confused over the options for synchronizing electronic flash with their camera's shutters. This section clears up that confusion. As you might know, digital SLRs can use a combination of electronic and mechanical shutters to control the length of time the sensor is exposed. An electronic shutter is just that The sensor is controlled electronically to allow it to capture photons for a fixed period of time. The electronic shutter is used for very brief exposures. The...

Finding RAW imageediting applications

Dust Reference Photo Nikon

Remember, to work with RAW files, you need an application that can read them. A variety of RAW converters are at your disposal. Some of these are provided by your camera's vendor and, as you might expect, work only with the RAW files for that line of camera. Unless you own several different digital cameras from different manufacturers that can produce RAW files, these proprietary converters might be all you need. Or, you can check out third-party RAW applications if you prefer. The following...

Creative use of telephoto tenses

Telephoto lenses have their own set of creative strengths and dangerous pitfalls. Keep these tempting applications in mind when working with your longer lenses and tele-zooms 1 Compression Telephoto lenses compress the apparent distance between objects, making that row of fence posts appear as if each post is only a foot or two distant from the next. Moviemakers use this effect all the time to make the hero appear to be racing bravely between speeding cars while crossing the street, when...

Taking night shots at short shutter speeds

You might want to avoid very long shutter speeds and prefer the shorter shutter intervals a higher sensitivity higher ISO setting affords for any number of valid reasons Perhaps you don't want to spend 30 seconds or more making a single exposure because of time constraints or physical conditions rain, muggers, and so forth . You might want to take as many photos as possible in available darkness. Or, you'd rather avoid the light streaks from moving cars or other illuminated objects that a long...

Reducing noise in your photos

Noise is that grainy look digital photos sometimes get, usually noticeable as multi-colored speckles most visible in the dark or shadow areas of an image Although you can sometimes use noise as a creative effect, it's generally a bad thing that destroys detail in your image and might limit how much you can enlarge a photo before the graininess becomes obtrusive. The most common types of noise are produced at higher sensitivity settings. That's because cameras achieve the loftier ISO numbers by...

Improving Your Photography with a dSLR

The differences between digital SLRs and the camera you were using before you saw the light will depend on where you're coming from. If your most recent camera was a point-and-shoot digital model, you know the advantages of being able to review your photos on an LCD an instant after you took them, and you also know the benefits of fine-tuning them in an image editor. If you're switching to a digital SLR from a film SLR, you are likely a photo enthusiast already and well aware that a single lens...
