I've now shot 8 rolls of Tri-X 35mm, and developed it in Accufine's Diafine 2 bath developer. I think I like this stuff a lot! It gives a 1 stop push in film speed to most regular BW films (it only gives a 1/3 to 2/3 push to tabular grain films), but it gives a 1.5 to 2 stop push to Tri-X (ISO 1250 to 1600) without really looking like it was pushed. It deals with contrasty lighting very well. 2 bath developers sort of develop to the proper contrast automatically. And it's super easy to use. You don't have to worry about temp too much; just make sure all the chems are about the same, but it doesn't have to be at 68 degrees (F). No pre-wet. Pour in solution A. Invert your tank twice every minute for 3 min. Pour solution A back into it's jug. Pour in solution B. Invert your tank twice every minute for 3 min. Pour solution B back into it's jug. Rinse with water for 30 sec, and then fix and wash as usual. The capacity is near infinite. It doesn't wear out. Eventually you have to buy more because you are slowly losing a bit of chemistry every time you use it, but it can sit on your shelf in a sealed jug for years and still be good. In fact, some people claim it gets better 6 months after it was mixed. The only disadvantage that I can see with it is that it doesn't allow for development changes such as increased agitation, temp, concentration etc... There is only one film speed/contrast/tonal range (depending on film type) available. I'll scan some of the negs and post them tonight in the 'Photo Gallery'.
