Grayscale only has one channel, and the TOTAL number of bits available is only 8 bits per pixel, for 8 bit grayscale. For color, there are three color channels available, and therefore the TOTAL number of bits per pixel is actually TWENTY-FOUR using 8 bit/color pixels, instead of simply 8. 24 bits is 2**24 or 16,777,216. 8 bits is only 256. Hum, we have a few orders of magnitude in available tones to work with here... > And the colour separations on RGB (the > 256 colour 8 bit ones, are fine to work on) - yet not on B&W. > P.T. who? This statement is nonsensical, as it clearly shows you have misconception of the concepts involved here. > Or they might want to follow youre religion, and miss out on > enlightenment. I would hardly call your "position" enlightened. You've got clear misunderstanding of some of the concepts here, as well as apparent lack of experience. If I were you, given what I've read here, I'd strongly suggest you either try to learn something, instead of try to rationalize your position, because you can learn something here if you want to. Instead of fussing, you ought to post a raw image, and then an image manipulated using only 8 bits and one using 16 bits, that shows this problem you are citing. If you can't then what you claim is simply myth.
