The Washi P is a black and white film. Washi is responsible for the production.
The panchromatic film is cast by hand on a transparent polyester carrier. According to the manufacturer, the film is to be exposed to ISO 100. Due to the lack of a protective layer against overexposure, a corresponding effect can occur with strong lights in the film. It occurs more strongly with 35mm film.
It is important to place the film in the camera in the shadow. Furthermore, one should not take too important pictures on the first pictures, as there is a danger of light leaks.
Development of the film
The Washi P must be developed in a black and white developer. Black and white development can also be done at home with the appropriate equipment and chemistry. However, it is also possible to bring the film to a development laboratory. Complete darkness is important when developing the black and white film.
