RETROPAN 320 soft is a negative black and white film with fine grain, good resolution and edge sharpness. The film offers a broad range of half tones and soft light presentation which makes it suitable for photography and subsequent contact printing or “retro” style enlarging of negatives (photographs of still lives, architecture, experiments, landscapes, portraits, etc.). The sensitivity of the film is ISO 320/26° but its great exposure latitude provides very good results also with overexposures by min. 1 EV (ISO 160/23°) and underexposures by 2 EV (1250/32°). For positive development, variable contrast enlarging papers are recommended – Fomabrom Variant, and papers of warm tones of both base and silver – Fomatone MG Classic. Other types of black and white enlarging papers, however, may also be used; in order to emphasize the “retro” effect or the vividness and plasticity of the image, they may be further toned – e.g. using Fomatoner Sepia brown toner.
