Film Washi "S" 50 ISO 35mm x 36 exp. - Re-purposed Specialty Film

Model: 4460351
Manufacturer: Film Washi

In Stock

Launched in 2013 and based in Saint-Nazaire, France, Film Washi is the world’s smallest company to produce photographic materials. Specialized in handcrafted film making and industrial film conversion, Film Washi offers a wide range of unique and innovative films.

Film Washi's "Specialty Films" are coated by machines in other factories - but are not made for standard photography. They may have been designed for exposure through automatic machines, like motion picture sound or leader film, or even not intended for visible light, like X-ray films. Some of these films are designed for specific governmental or military uses, like surveillance films. However, these films can be hacked from their intended use - for artistic or fun purposes! That is why Film Washi converts them to standard formats to make them usable in classic cameras.

Film "S" is a film used by motion picture professionals for sound recording, which requires very fine grain and ultra high definition. This sharpness is achieved by a special anti-halation layer located between the film's base and the emulsion layer - its usually in back layer for ordinary films. Film Washi has rated this film at 50 ISO. 

"S" is recommended, when you want to combine almost no grain with very high contrast.
