cassette contanins the developing agent.
Polavision movie film is an additive color film, as
the Dufaycolor, Autochrome Lumičre 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.
