Fomaspeed Variant 313 Variable Contrast RC Paper is a black-and-white, variable-contrast glossy-finish enlarging 17,8x24cm photographic paper on a resin-coated (RC) paper base. Its contrast can be varied in a large extent from extra soft up to ultra hard by using color filters at exposure. This paper is designed for amateur, commercial and artistic photography as well as for other applications.
Fomaspeed Variant 313 Variable Contrast RC Paper features a very rich half-tone scale over all contrast grades, a shining white paper base and saturated blacks. This paper is manufactured using silver chlorobromide emulsion that gives neutral-to-medium warm tone to the silver image. Developing agents incorporated into the emulsion layer facilitate rapid machine processing and a shortening development times in manual processing to 60-90 seconds at 20C. Due to the resin-coated paper base and a thin emulsion layer, the time necessary for development, fixing, washing and drying is considerably shortened and the comsumption of processing baths and washing water is reduced.
