RETROPAN 320 is a panchromatically sensitized special black-and-white negative film with fine grain, good resolution and contour sharpness. The film has a wide range of halftones and soft light rendering, therefore it is suitable for photography and subsequent contact copying and enlargement of negatives in the "retro" style (still life, architecture, experimental, but also landscape, portrait, etc.) The nominal sensitivity of the film is ISO 320/26°, but its wide exposure flexibility provides very good results even with overexposures of min. 1 EV (ISO 160/23°) and underexposures of 2 EV (ISO 1250/32°). For making positives, we recommend enlarging papers with variable gradation - Fomabrom Variant and papers in a warm tone of the base and silver - Fomatone MG Classic 131, 132, 133, but other suitable types of black and white enlarging papers can also be used.
