I feel embarrassed and need to retract most of what I said above regarding T-Max 100 and 400 films. I just rechecked my TMY negatives and they do indeed have a mostly clear base with only a very slight tint. Furthermore, I went back and found some of my TMX negatives and the base is quite clear.

Most likely I was thinking of the my test strip used to test my fixer that was in the fixer only long enough to determine a fix time. I guess that is what I get for trying to post something at work in a hurry when what I need to refer to is at home.

Perhaps I should shoot more T-Max film and get a better feel for it.
