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. In this sense, it was somewhat similar to the much earlier Dufaycolor process.
