Notes on this view:

This is an example of PolaChrome, an instant 35mm slide film introduced by the Polaroid Corporation in 1983. The process combined screen plate and diffusion transfer technology allowing consumers to rapidly produce color transparencies at home. After exposure, the film cartridge and a pack of processing chemical were placed in a Polaroid AutoProcessor, which required hand cranking, or a PowerProcessor, which was motorized. These devices were made specifically for processing PolaChrome. The processor unrolled the film and spread processing chemicals evenly over its surface. Development occurred in 60 seconds after which the film could be cut and mounted for viewing. Polaroid discontinued the Polachrome system in 2002 after limited commercial success.
