I have recently tested the new TMAX 400 in 4X5 sheets and have come up with an interesting observation. I have used TriX, the old TMAX and some of the Ilford films. When targeting Zone I at .1 above film base, all of these films want to be shot at something slower than box speed. However, I am finding that the new TMax is actually a little faster and my tests indicate that I should rate it at box speed. Before I get worried about my chemicals (I'm using HC-110), I thought I'd ask the group here if anyone has similar experience. Has anyone else found that this new film is actually a little faster than the old TMAX?
