Fomapan 100 Classic is a panchromatically sensitized, black-and-white negative 35mm film designed for taking photographs. The film meets high requirements for low granularity, high resolving power, and contour sharpness, and a wide range of halftones. FOMAPAN 100 Classic has a nominal speed rating of ISO 100/21o, but due to its wide exposure latitude, the film gives good results even when overexposed by 1 EV (exposure value) (as ISO 50/18o) or underexposed by 2 EV (as ISO 400/27o) without any change in processing, i.e. without lengthening the development time or increasing the temperature of the developer used.

To make prints or enlargements, Fomabrom- and Fomaspeed-type enlarging papers are recommended; however, all sorts of black-and-white enlargement papers can be used.
