This is the first Polaroid instant picture camera.

The sensitive material comes in two parts, a roll of negative film is loaded at one end of the camera and a roll of positive paper at the other end. The processing chemicals, comprising a developer and a silver halide solvent, are held in pods attached to the positive paper. After an exposure the free ends of the negative and positive rolls are pulled through a slot in the base of the camera, the pods are broken and the solution is spread over the negative and positive material. After development the print can be removed through a door in the back of the camera. Once removed, the monochrome print was generally coated with a glaze. The close proximity of the negative and positive allows unused silver salts to pass across the developer to the positive print.
