Sal: I developed Delta 400 (@320) and TMX (@80) in 35mm size: 9'30" @ 70 for Delta 400, agitation for one minute at outset, then 10"/min thereafter; 8'-0" for TMX, same agitation. The Delta 400 time was very good, printing at #3 on my Aristo VCL4500 cold light head. TMX was close to correct, but probably would have been better with 30 to 60 seconds more, say, 8'-30" @ 70.(posted 8252 days ago)Of interest, TMX, which I find extremely fine grained in my normal developer, exhibited more grain than I expected; Delta 400, however, showed exceptionally fine grain. Comparing the two, grain-wise, displayed only a slight advantage to TMX, certainly less than one might expect. However, TMX was *really* sharp, and showed none of the diffused look so many complain about. The grain difference might be attributed to TMX being slightly underdeveloped; I didn't test enough to really say for sure. In any case, both films looked terrific in this stuff. It has some of the look of Rodinal, but even sharper and finer grained. Hope that helps to give you a better idea of what you can expect.
