I wouldn't expose TMX @ EI100 if I was going to process in Rodinal. If the film is already exposed, try Xtol 1+1. If you haven't exposed it yet, I'd start with the suggested exposure/processing data in the Agfa Rodinal datasheet (look at http://www.agfaphoto.com/library/datasheet/chemicals/rodinal.html). I found EI64, Rodinal 1+50, 12 min was pretty darn close, but I prefer dilute Xtol for T-Max.(posted 9548 days ago)Dana K6JQ Dana@Source.Net
