FILM ASSEMBLAGE WITH PRE-EXPOSED FILM AND METHOD FOR FORMING THE SAME |
摘要 |
During manufacture a film unit has one portion masked while it is exposed to light in a second portion to form a latent image of indicia on the mask. A pod of liquid developer is attached to the pre-exposed film unit and together they are mounted within a cassette. The cassette is inserted into a camera where the previously unexposed portion of the film unit is exposed to image bearing light while the pre-exposed portion of the film unit is masked from said light. The pod of developer liquid is passed through a pair of rollers to rupture the pod, spread the developer liquid between the layers of the film unit, and develop the two latent images as a single photograph.
