The 100' long, 35mm roll of Fomapan R100 Black & White Reversal Film from Foma is an ISO 100 panchromatic-sensitized, black-and-white reversal film for capturing black-and-white transparencies. It is distinguished by very fine grain, high-resolving power and contour sharpness, and higher contrast.

The spectral sensitization allows transfering color tones into grayscale when exposed in daylight, and to simultaneously make full use of the film speed when exposed in artificial light. Due to a very efficient anti-halation layer, situated between the base and emulsion layers, the film features very good resolving power and high contour sharpness. The anti-halation layer will decolorize during processing.
