I have found that Rodinal 1:50 works well with TMax100 in 4x5 ; at EI80, try 13 minutes at 20oC. For something like N-1, rate at EI50, and process for 10.5 minutes. Rodinal will also take out all the anti- halation dye.(posted 8733 days ago)I have not obtained good results with TMax100 and PMK Pyro.
I've never tried TMax RS ; can you share your EI's / developing times?
