Tasma KN-2 — black and white cine film 135, 36 exposures, ISO 8–12, expired 03/1973

Tasma KN-2: old black-and-white cine film for experiments

Tasma KN-2 is a Soviet black-and-white 35mm cine film with a low speed: the label gives ISO 8–12 (working range 6–25). This batch is heavily expired material from 1991, so treat it as experimental vintage stock rather than predictable fresh film.

Reference data for fresh KN-2 mentions high resolving power of about 100 lines/mm and use in bright daylight outdoor shooting. In practice, film this old may show fog, reduced contrast, unstable speed, and more visible grain. That is part of the appeal: the result can be raw, graphic and very different from modern emulsions.

Best for

• photographers who enjoy testing old Soviet and cine film stocks;

• bright daylight, tripod work or cameras with manual exposure control;

• frames where fog, texture, unpredictability and vintage defects are welcome.

I recommend test frames, with exposure and development adjusted for the specific roll. This is a character stock, not a guaranteed clean commercial film.

Best before: 03/1973 (per the label) — the film has expired.
