Books

You can find dozens of great educational books on the market, including my own National Geographic Photography Field Guide Secrets to Making Great Pictures, co-authored with Robert Caputo. Sybex, the publisher of Mastering Digital Photography and Imaging, also offers a growing library of digital photography and imaging titles on a variety of topics. Following are some recent and upcoming Sybex books. Color Confidence The Digital Photographer's Guide to Color Management, by Tim Grey Mac Digital...

Flash Exposure Compensation Control

Some cameras (and accessory flash units discussed later) include a feature for reducing the intensity of flash. Some manufacturers refer to this control as Flash Exposure Compensation or FEC, my own preferred term other manufacturers call it a flash power or flash output control. It can be useful for reducing flash intensity for a gentler burst of light that fills in shadows but does not overpower the sunlight. Experiment in outdoor photography with a -0.5 and a -1 setting you'll soon know...

Mail Considerations

As mentioned earlier, any image file that you distribute via e-mail should be small, particularly when you plan to attach several images to a message. Otherwise, you may find that the attachments take too long to send, and the recipient encounters very long download times. Unless the recipient wants to print the image, there is no need to send a file that's larger than about 100KB after it is compressed. Many recipients of an attachment will never open the JPEG with image-editing software they...

Using Adobe Gamma for Basic Calibration

To adjust the appearance of your monitor display, use Adobe Gamma (see Figure 9.3) or the Mac ColorSync Calibrator. The software generates a color profile that describes the color behavior of your monitor. Make the correct monitor adjustments and settings in the utility and the new profile should allow the image editor to generate displays with greater accuracy. You'll find discussions of profiles throughout this chapter. A profile is a file that describes the color behavior of a device, so...

Semiautomatic Modes

Two semiautomatic modes are available with many cameras Shutter Priority, often abberevi-ated as TV (for Time Value, not television) and Aperture Piority mode, often abbrevieated as AV (Aperture Value.) If you select Shutter Priority (TV) mode, you can set a desired shutter speed the camera responds by setting the corresponding aperture to maintain correct exposure. In Aperture Priority (AV) mode, you select the aperture (or f stop), and the camera responds with a suitable shutter speed for...

Acknowledgments

Although only one name is on the cover, this book was not a solitary venture an entire team made it possible. I want to thank the staff at Sybex, including Bonnie Bills who motivated me in the early stages, Dennis Fitzgerald who patiently but persistently kept me on track, editor Willem Knibbe who daily challenged me to make the text more incisive and readable. Others who contributed their talent include Mark Ong, Susan Riley, Pat Coleman and Rodney Koenke. I am particularly grateful for the...

SLR Camera Capabilities

All the features mentioned in the Common Compact Digicam Features section apply to digital SLR cameras, but there are additional capabilities. You'll often find more ISO options (higher and lower), numerous custom functions for tailoring camera operation to your own preferences, extras such as depth-of-field preview for visually assessing the range of apparent sharpness at any f stop, high-speed continuous AF for tracking fast motion, and more. All these are fairly typical SLR features,...

PlugIn Software for Image Enhancement

As mentioned earlier, many all-purpose image-editing software programs can be made even more versatile, with the addition of software available from after-market suppliers. Although they are referred to as Photoshop plug-ins, many (but not all) are compatible with other programs, such as Corel Photo-Paint, Microsoft Digital Image Pro, JASC Paint Shop Pro, and Ulead PhotoImpact. (If any of the plug-ins are of interest to you, check the distributors' websites for up-to-date compatibility...

Dpi On Groundglass

Printer resolution is entirely different from image resolution. Image resolution refers to the density of pixels in a digital image. Inkjet printers produce the best quality when the image file is set to a resolution of about 300 ppi (pixels per inch). Although ppi is the correct term in this usage, it is often called dpi (dots per inch), and that can become confusing. Printer resolution, selected in the printer driver software, is correctly expressed in dpi, because dpi refers to the number of...

Using a Tablet and Stylus for Image Editing

For many photo-editing tasks, you'll find that you need to exercise precise control over the mouse. In those situations, you might prefer to use a stylus because you manipulate it with your fingers as you would a pen, rather than moving your whole hand with a mouse. In addition to allowing more control over cursor movement, the stylus is pressure sensitive. This allows a whole new area of control. Applying varying degrees of pressure can control the size, hardness, or other attributes of the...

How To Use Jasc Software

One of the most powerful image-editing programs available in the affordable category, Paint Shop Pro version 8 or later costs only 99 and is sometimes compared to Photoshop 7, the professional Adobe software that was available until the release of Photoshop CS. Although Paint Shop Pro see Figure 4.3 does not include all the functions of Photoshop 7, it is impressive, boasting numerous advanced and sophisticated capabilities. In addition to extensive Figure 4.3 Offering many professional-caliber...

Color Depth

Also called bit-depth, this factor determines the number of colors that a scanner can see. The higher the bit-depth, the more accurate the colors in the scanned image, with full rendition of the subtle differences between similar colors. Most scanners offer color depth of at least 8 bits per channel for red, green, and blue, the three colors used in imaging. This is often denoted as 24-bit color depth in the specifications. This level is adequate for most purposes, because it records true color...
