Kodak Professional T-MAX Film is a continuous tone, panchromatic, tabular-grain black and white negative film made by Eastman Kodak. It is sold in two speeds: 100 (TMX) and 400 (TMY-2). Kodak also sold an 3200 speed film (TMZ). The 100 and 400 speeds are given as ISO numbers, but the 3200 were sold as a multi-speed film. T-MAX 100, due to its very high resolution of 200 lines/mm, is often used when testing the sharpness of lenses.
In early 2002, Kodak replaced their similarly titled Kodak T-MAX Professional Film with Kodak Professional T-MAX Film. There was also a slight change to the packaging. The main difference between the two are in the processing times.
In October 2007, Kodak revised the 400-speed film, giving it the name TMY-2 instead of TMY. In the process Kodak increased the resolution from 125 lines/mm to 200 lines/mm, which is on par with their 100 speed film.
The 3200 speed is actually nominally 800 speed. It has uses in surveillance and other work where it can be given a pushed exposure index between 1600 and 25000. It is also used in X-ray cameras in high-neutron environments where CCDs are unviable due to noise induced by neutron impacts, such as the National Ignition Facility.
On October 1, 2012, Kodak announced the discontinuation of Kodak Professional T-MAX p3200 film due to the high expense of manufacturing it for only a limited user demand.
