Polavision was a home movie film system launched by Polaroid in 1977. What set it apart from other home movie formats like Super 8 was that Polavision offered quick developing at home in just a few minutes.
The film was contained in a cartridge for easy loading in the handheld camera, and this had two reels for the film as well as a small lens and prism for projection as the film remained in the cartridge when projected. Unfortunately, the cartridge only held enough film for around two and a half minutes of recording.
The film was in colour (using the additive process), but there was no sound, and the images were criticised for being murky. The film was not very sensitive, and required a lot of light to film successfully.
Developing and projecting the film required the Polavision tabletop projector that projected the images onto a translucent screen. Developed film however can be extracted from the cartridge for use on a Super 8 projector.
The Polavision system was a commercial failure and lost Polaroid a considerable amount of money. As well as having to compete with Super 8, Betamax and VHS home video cameras were becoming available (though at this stage still very expensive and requiring a separate portable recorder).
It was withdrawn in 1979.
