FP4+ in Pyro PMK - Zone System Development Times

[Mike McMullen]

This is one of my favorite film/developer combinations, have used it for years using Zone System with 2 1/4. Now venturing into 4 X 5 and working on new times for "N", "N+1", etc., with the BTZS tubes. 75 degrees F at 8 1/2 min. looks to be about right for "N" on my densitometer, but I'd like to hear if others have similar results, and their favorite film for pyro developer using 4 X 5? Thanks. Also, I'm looking for a good used 20 x 24 easel. Thanks.

9 min for me at 100asa in jobo at 68 degrees for diffusion enlarger.

It depends on what you want to print IMO, what your densities will need to be. If your'e scanning and/or making GSP's then you can have a thinner neg. than if you wanted to print alt. processes.
