The Washi A 12 is a black and white film. The material on which this film is based was actually developed for reproduction in the production of motion pictures. It is characterized by fine grain and high contrast.
It is offered to photographers by the company "Film Washi" from Saint-Nazaire in France. The Washi A 12 is orthochromatically sensitized and cast on a polyester base. The maximum spectral sensitivity is 580 nm.
It is currently only available for 35 mm cameras. It should be exposed between ISO 2 and ISO 12, depending on the development. This must be done in a suitable black and white developer.
