I moved to TX about 3 years ago and I've done very little film work (no basement for a darkroom and other complications) since then. W/o looking at my notes, I want to say that I used something like 20 ml ea of A and B of Pyrocat HD in 1 liter of deionized/distilled water for developer, and made fresh developer for each sheet of film (5x7 or 8x10). Part of the reason for choosing Pyrocat HD is that the stain is UV opaque but not visual light opaque so, in theory, I could put my negatives in an enlarger as well as use them for contact prints (my preference).
