Foma Retropan 320 Soft 35mm Black and White Negative Film, 100' Roll

RETROPAN 320 soft is a panchromatically sensitized special negative black and white film with fine grain, good resolution and contour sharpness. The film is characterized by a wide range of half tones and soft light 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 320/26deg. but its wide exposure latitude provides very good results also when overexposed by min. 1 EV (ISO 160/23deg.) and underexposed by 2 EV (1250/32deg.). For turning into positives variable contrast enlarging papers are recommended - Fomabrom Variant and papers of warm tones of base and silver - Fomatone MG Classic 131, 132, 133, 532-II, 542-II. Other types of black and white enlarging papers may also be used. In order to emphasize monochromatic tonality or the vividness and plasticity it is possible to tone the papers - e.g. using Fomatoner Sepia brown toner.

Base
A gray or gray-blue cellulose triacetate base 0.125 mm thick.
