Kodak has also released a black and white file (TMAX T400CN) which is processed in C41 chemistry. I have just tested a dozen or so rolls, metering at 400, and found the grain to be surprisingly fine and the tonal range to be excellent. The film is supposed (according to Kodak) to be pushable to 3200, but I have not tried any pushing at all.(posted 9850 days ago)
