rodinal questions
Andrew, this may or may not be of use to you, for many years I used TMax 400 (TMY) developed in Rodinal at 1:100, excellent results for me at between 17-18 minutes with standard agitation 10 sec each minute. This is at 20 deg. Very good edge effects. Not too sure about the enlargement sizes you want with 35mm though, all my films were 120 & 5x4. I have unreliable stats for TMax100 so won't quote them. Good Luck.
