I'm jumping off the cliff this weekend and processing some film in Pyrocat. For the film test is 1:1:100 for 9 minutes at 70 degrees a good starting point for a film test? The times in the Photographers formulary are for drum processing and are roughly the same as BPF200 in d76 I will be tray processing with intermitant agitation (or should it be constant?) The film is BPF 200 exposed at 100 I am most concerned with expansion development because my SBR's have been averaging 3. Yep BW in the SW can be a pretty flat adventure without expansion development.
