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?
I have tested the new TMY in several developers next to the old TMY and film speed was virtually identical.
