I'd have to admit, I like TMAX's sharpness, but it is very easy to ruin a picture with overdevelopment. I have expermented with various developers, i.e. HC-110 (dil b), Ilfosol (1:14), TMAX developers (which I might add were terrible!).(posted 9039 days ago)I treat TMAX 100, like it was ISO 25 film. The film responds well to XTOL 1:1. Also tried XTOL 1:3, too grainy. Make sure you allow for the increase in exposure by cutting back the development time. Kodak's web site gives time for exposures at ISO 100, 50, and 25, use these.
