[FONT=Arial, Helvetica, sans-serif]Adobe RGB squeezes colors into a smaller range (makes them duller) before recording them to your file. Special smart software is then needed to expand the colors back to where they should be when opening the file. [/FONT]
[FONT=Arial, Helvetica, sans-serif]Since Adobe RGB squeezes colors into a smaller range, the full range represents a broader range of colors, if and only if you have the correct software to read it. [/FONT]
[FONT=Arial, Helvetica, sans-serif]Played back on most equipment, the internet or email, the colors look duller, and when played back with the correct software, the extra chroma gain required adds a little chroma quantization noise. [/FONT]
[FONT=Arial, Helvetica, sans-serif]This is the example above. The bottom grad is what an Adobe RGB file looks like when interpreted as sRGB, which is what happens over the internet, email, or most printers unless you're printing directly at home from Photoshop. Printed correctly the Adobe RGB grad looks the same as the sRGB grad, so I asked myself, why bother? [/FONT]
[FONT=Arial, Helvetica, sans-serif]If you use Adobe RGB you will have to remember to convert back to sRGB for sending your prints out or sharing them on the Internet. Otherwise they look duller than sRGB! [/FONT]
[FONT=Arial, Helvetica, sans-serif]If you have the right software to re-expand the colors you theoretically might have a slightly broader range of colors. However, if at any point in the chain you don't have the right software and haven't attached the Adobe RGB profile you'll get the duller colors as recorded![/FONT]
[FONT=Arial, Helvetica, sans-serif]Web browsers don't have, and print labs rarely have, the right software to read Adobe RGB This is why people who shoot it are so often disappointed. Even if a place has the right software, if you forget to add the Adobe RGB profiles to your files these places will read them incorrectly and you'll get dull colors. [/FONT]
[FONT=Arial, Helvetica, sans-serif]Adobe RGB may be able to represent a slightly larger range of colors, but no screen or print material I've used can show this broader range, so why cause yourself all the trouble? I've experimented with 100% saturated grads in these two color spaces and never seen any broader range from Adobe RGB either on my screen or on SuperGloss Light jet prints.[/FONT]
