My experiment is still on going, but I'd like to solicit opinions from folks far more experienced here. I have been having problems with getting what I want from my chosen 35mm film+developer, Tmax400-2 + XTOL. I have shot them with EI200, EI400, developed full strength, 1:1, regular time per chart, -20%, -15%, etc. The result seems to be too high in contrast with not much of smooth middle gray. It goes from shadow to highlight too quickly. Developing it at -20% to lower the contrast ended up being too thin, -15% showed not enough contrast but also no smooth middle gray. For lack of better way to express the result, the result is "jumpy" from shadow to highlight. Now, I just shot my first roll of MEDIUM FORMAT film and developed it. This time, the combination was Tri-X 400 developed with D-76 1:1 -10% dev time. The result was fantastic. It had the level of contrast I liked and very smooth and long gray tones. This was the result I was looking for. Now, the question part: 1) What's my problem with Tmax-400 and XTOL combination? 2) Are these the expected result? 3) Is this the result of different enlargement factor? (135 vs 120) I have a frig full of Tmax. If there is a problem with my shooting or processing, I'd like to keep using them. I'm very tempted to get Tri-X for 135 and/or process Tmax in D-76... but I'd like to get my bearing before I start mixing matching. Thank you.
