Polavision was an instant movie camera system launched by Polaroid in 1977.
Unlike other motion-picture film stock of the time, Polavision generated color using an additive process. It consisted of (essentially) a black-and-white film base and three-color filter layer.[1] In this sense, it was somewhat similar to the much earlier Dufaycolor process.
The Polavision cartridge was a small rectangular box with the film reels self-contained, along with a small lens and prism for projection at an open gate. Unless viewed in a Polavision viewer, the only way that developed films can be viewed was by destroying the cartridge and projecting in an super 8mm projector, a super 8mm telecine system, or other transferring procedures. The film format was similar to the Super 8mm format.
Due to the light-loss caused by the filtering layer (only one of red, green or blue was let through for a given portion of film), the resulting film had relatively low light sensitivity (40 ASA) and the resulting footage was much denser than with other processes.[1] As a result, Polaroid designed a standalone table-top projector/viewer, which was intended to reduce the problems inherent in projecting such dense film.[1] The viewer used a translucent screen, projecting the image from behind, but critics from publications like Consumer Reports called the images "murky and dark." The format was used by artists, including Charles & Ray Eames, and Andy Warhol.
In addition to the density problems, the process was late to market and had to compete with upcoming videocassette-based systems like Betamax and VHS. Unlike videotape, Polavision films, once developed, could not be reused nor played on a television. Polavision proved to be an expensive failure, and most of the manufactured equipment was sold off in 1979 as a job lot at a loss of $68.5 million. In the wake of those losses, Polaroid chairman and founder Edwin H. Land resigned the chief executive position in 1980 and left the company two years later. [2]
Former Polaroid freelancer Paul Giambarba remarks
- "I tried using the product but it was obviously a turkey compared to anything I was using that Kodak offered [..] Instant movie film was an engineering achievement but it's precisely what separated Polaroid techies from Polaroid pragmatists. There just weren't enough customers out there on whom to work the magic."[3]
Polachrome and Polapan
Polaroid's instant transparency system for still photography was introduced in 1985, and was based around the AutoProcessor.[4]
Polachrome was an "instant" 35mm color transparency film. It was descended from the Polavision system and used the same additive color (filter) process. One difference was that with Polavision, the negative layer remained as part of the film after processing. It was intended to turn transparent after a short while, but the process was reportedly imperfect, reducing contrast. With Polachrome, the black negative layer was discarded after processing.[1]
Polaroid also produced a black-and-white instant slide film called Polapan.[5] PolaPan is a contraction of Polaroid and Panchromatic and it was additionally used in connection with Polaroid picture roll print films Type 42 PolaPan 200 (200 ASA film speed) (also Type 32) and Type 44 PolaPan 400 (400 ASA film speed in Daylight). Polaroid also produced PolaScope film Type 410 10,000 ASA high contrast specificaly for photographing oscilloscope ("scope") traces.
