Fomapan 100 Classic is a panchromatically sensitized, black-and-white negative film designed for taking photographs
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 100/21° but due to its wide exposure latitude the film gives good results even when overexposed by 1 EV (exposure value) (as ISO 50/18°) or underexposed by 2 EV (as ISO 400/27°) 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, Extrabrom- and Fomaspeed-type enlarging papers are recommended; however, all sorts of black-and-white enlargement papers can be used
