Yves,
You are correct, there are a couple of typos in the paragraph—it should have
read:
Let's assume that a digital negative can have a maximum of 256 possible tones
of density (If that is ok with you) and that a radical curve is going to
reduce the number of tones from 256. However let's just assume that a curve that
is not radical will do the job. Let's also assume that the negative's density
range matches the exposure scale of the gum mix before the curve is added.
Now, let's assume that by now I have forgotten what the hell the original
question was. hehehehe
Best Wishes,
