I tried pushing acros a while back when I didn't know what I was doing and it didn't turn out. Recently I've been successfully pushing Tri-X (and the same method, I understand, should work basically the same for Acros at these times and dilutions) with Rodinal 1:100 following these directions: http://www.rangefinderforum.com/foru...6&postcount=47
For future reference, the text:
I don't know quite how linear push processing times are, but he adds an hour (120 min total) to his push times to get a 4 stop push (so 15min per stop). I was going a little bit over 30min (closer to 45) to do a 2 stop push (just to be safe). Other people will have more objective suggestions, I lean in my developing times.
