    Since sRGB was originally developed for display purposes, many digital workers assume that it’s only useful for the Web and screen display. That’s a very limiting attitude. There’s no question that when dealing with precise colors in a specific color range, Adobe RGB has an edge over sRGB.

    But sRGB offers high-quality results, too. Because it’s a simpler color space, it can help photographers get to a print they like faster than working with Adobe RGB, as the slightly more limited color space can be easier to work with. In addition, since many small digital cameras only offer sRGB, saying you must use Adobe RGB ignores the quality results possible from these cameras.

    New digital photographers are disappointed in what they first see on the screen with Adobe RGB since this color space spreads out the colors and tones more, sometimes making the image look dull. When they started using sRGB, they were much happier.

    It’s interesting to me that pro photographers who used to only work with slide film never complained about the smaller “color space” of slides compared to print film (print film has a far greater tonal and color range than slide film). They liked its colors and tonal rendition. Now, some of these same photographers will absolutely insist that they must have the larger color space of Adobe RGB. Such arguments are never about the photography, however, but about numbers, i.e., how much bigger the Adobe RGB color space was.

    This is really what the sRGB and Adobe RGB choice is about—personal preferences. If you like the results that sRGB gives you, you can use it and forget those books that chastise you for even thinking of anything else. If you like what you get from Adobe RGB, then use it and make great images, too.

    Attack Of The CD-Eating Rot
    “CD rot” is an interesting misconception that’s based on real facts. Older, poorly manufactured CDs have had problems with the lamination of the top layer of the disc, where it chemically decays and “rots” from the edges, making the CD unusable. This became a big news story that went across the wire services nationwide and alarmed many, including photographers using CD-Rs for archiving images.
