Washi Film S is a slightly orthochromatic B&W film (up to 620 nm) used by motion picture professionals for sound recording. This film is characterized by a very fine grain and ultra high definition.
The superb sharpness is guaranteed by a special anti-halation layer located between the film's base and the emulsion layer while its usually in the back layer of most other black-and-white films. The film is now industrially spooled but still hasn't any DX code which you should keep in mind.
