You know what? Even if I was mistaken, you would still be an ass for calling me a liar. However, I am not mistaken, you just can not read.
256 tints of Red x 256 tints of Blue x 256 tints of Green give 16.7M tints of color. I used the term tints instead of shades because that is a more accurate color concept. Dmax is not exactly the same as Dynamic range, it ignores the min-white and just tells you what the max-black that can be recorded is. Furthermore, Shel asked that this all be explained in simple terms ignoring the technical details. I tried to do that. I may not have succeeded, but you, besides only being half informed, did not even try. Ciao, graywolf [EMAIL PROTECTED] ----- Original Message ----- From: J. C.
