• Polavision phototape cassette requires Polaroid Polavision Player for development and viewing: you could watch your film 90 seconds after shooting.

• Polavision movie film  is an additive color film, as the Dufaycolor, Autochrome Lumière or Finlay Colour. The illusion of color is formed by adding together proper proportions of red, green, and blue light. The film surface is made up of strips of alternating red, green, and blue filters. On the film base, they are imprinted microscopic stripes of color in triplets (4500 per inch). These filters act both during exposure and during viewing to reproduce color. Polavision  film in essentially black-and-white film that has been adapted for color by this clever mechanism.
