This is a 36 exposure roll of T-Max P3200 Professional Film from Kodak. It is an ISO 3200, continuous-tone panchromatic black-and-white negative film that combines high speed with finer grain than that of other fast black-and-white films.
Can be pushed/pulled from 3200 to 25,000 - Underexposing by three stops and using three-stop push-processing produces a further increase in contrast, graininess and additional loss of shadow detail. The results will be acceptable for some applications.
