Description

During photographing, light enters the cassette through a small hole (more often a lens group) and forms an image on the medium at the back of the cassette (relative to the light incident direction). The required illumination time is different according to the actual light intensity and the photosensitive capacity of the medium. During illumination, the medium is photosensitized.
