I'm a new convert to PMK, so this is probably a silly question but I'll ask it anyway: What are the qualitative differences between density from silver and density from stain?
Hutchings recommends returning the film to developer for two minutes after fixing, which intensifies the stain. So far I haven't done that because the negatives already appear to be plenty dense. In fact, I guessed they were overdeveloped (I was prepared for negatives that looked thin) but they printed much more easily than thinner negs developed in HC110. (I'm working in 4x5.)
Should I be developing less before fixing? If I cut back on the time and then return the negs to developer as Hutchings recommends, how will the resulting negative differ from the ones I am getting now?
