Pushing Tri-X in Rodinal can be rewarding, but the grain takes on a golfball sized structure. If you do it in Rodinal 1: 50 for 14 min at 70 degrees, it would be a starting point. If you find the grain too disturbing, try adding a 100 grams of Sodium Sulphite/ 1000 ml of ready developer. I.e 50 ml of Rod. and 950 ml of water in which you dissolved 100 grams of Sod. Sulphite. Agitate gently ( 2-3 inversions/min) and I usually do not use a stop bath ( Rodinal is a "surface developer and the acid stop tends to burn pinholes in the negs), just a 2 tankful water rinse and then fix as usual. I think that Rodinal is the oldest photographic product, in continious use. available today. It was introduced in 1889!. I use it for reference processing. When I have films I do not know anything about I usually run the first roll in Rodinal 1:100/ 20 min and I can then extrapolate the correct times from that. With films like Delta 100/ T-Max 100 and Agfa APX 100, you get very sharp and easily printed negs with this combination ( rate the films at 100ASA). I have even succesfully processed Neopan 1600 in Rod 1: 100/ 20 min. Very sharp, not fine grain but good compensation. The 1:100 doesn't work for pushing films, for that you need the 1:25 and 1: 50 dilutions. Good luck. Tom A
