Foma RETROPAN 320 soft is a panchromatic black and white negative film characterized by its fine grain structure along with good resolution and edge sharpness. Offering a wide tonal range and classic appearance, this film is particularly well-suited for contact printing and conventional enlarging applications, and its softer, mild contrast values are ideal for still lives, architectural, landscape, and portrait photography. Its nominal sensitivity is ISO 320/26° when processed in standard black and white chemistry or the recommended Retro Special Developer; however, its wide exposure latitude permits rating the film at one stop of over (EI 160) or two stops under (EI 1250) with good results.
