Kodak Professional Kodak TMAX 400 135-36 Film is a continuous tone, panchromatic black-and-white film for general pictorial use and it is especially useful for dimly lighted subjects, fast shutter speeds, for extended flash range, and good depth of field. It features fast speed (EI 400), extremely fine grain, and high resolving power.
It is a good film to push processes with shorter push-processing development time -- no increase for 1-stop push, shorter 2-stop push-times than other films require.
