Donald Miller said:Jeez. what staining developer is giving you that kind of variance? You had better package it because the folks that shoot films like Bergger BPF 200 for alt process would love to have something that would have that kind of stain effect.
I have encountered no staining developer that will give more than about .40 stain effect at a silver density range of 1.40
Pyrocat-HD on APX100. The negs are too soft for Ilford MG IV, and great on POP! No other film I've tried stains anywhere near as much as APX100. I still have about 100 sheets of 13x18cm left, and a little ore in 9x12cm and 6.5x9cm. Since those small sheets are mortly for enlarging, I've stopped using Pyrocat on them.
I have no idea what it does to Bergger 200, though.
Similar is redevelopment in pyro/soda (no sulfite) which I've used to boost contrast for POP, too.
