FWIW, here are tow different shots each made with TMAX 400 and Neopan 400. Both rolls were developed in XTOL 1:1. Different tanks but in the same session I used my RB67 and had two backs. A 120 back loaded with Neopan 400 and a 645 back loaded with TMAX 400. I don't have 2, 120 backs... I used the same body, lens, tripod, lighting, f/stop and speed for each. Only change the back for each shot. I thought the results were interesting and showed the difference between the two films.
