Mark,

I'm sorry Mark, I don't get it, "define parameters" like you do here and from a person who wrote a highly regarded book on the subject. What's a "tones of density"? Ok, I figured that one out. I'm beginning to think that like me english is not your forte and it would explain a lot of things like the para below where I see more confusion then definitions.

Regards
Yves

(If that is ok with you) and that a radical curve is going will >reduce the number of tones from 256, so let's consider a not so radical curve. Let's also assume that the negative matches the exposure scale of >the gum mix before the curve is added.
