This is exactly the paradox for me - how to avoid making the print look flat with shadows being bumped up the Zone. Using Grade 3 does not really help. Maybe it is in the developing times or the developer used. In any case, why shouldnt my so called "thinner" negatives not print better on AZO? They look great on the lightbox although not as dense as those that I add extra exposure and devt. They certainly have nicer contrast.
