Polachrome was a color slide film. It was descended from the Polavision system and used the same additive color (RGB filter stripe) process. One difference was that with Polavision, the negative layer remained as part of the film after processing. It was of low optical density (max. 0.3), but nevertheless reduced the contrast of the image. With Polachrome, the negative layer was discarded after processing.[1] Marketed broadly, it was touted to professional photographers for making test shots to evaluate a setup before final shooting was done with their usual film. Its distinctive muted color rendition and the line structure visible in enlargements won it a small following as a unique artistic medium in itself. It remained in production for nearly 20 years.
PolaPan was a monochrome ("black-and-white") slide film.[12] "PolaPan" is a portmanteau of Polaroid and Panchromatic. The PolaPan name had also been used in connection with Polaroid 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).
Polablue was a slide film with a particular blue color cast.
Polagraph was a high-contrast color transparency film intended for reproducing subjects like graphs or diagrams.
Polaroid AutoProcess slides could be viewed or projected in the same way as 35mm slides made with conventional films.
