lenticular colour photography

Definition: Additive system colour photography. * Based on system of small lenses and filters arranged to separate colours into separation primaries of red, blue and green. * Best example is Polaroid Polachrome film which uses stripes of red, blue and green filters (with some light-gathering power) exposing onto panchromatic film. After processing, a positive black & white image corresponding to exposure through the filters -- e.g. red light through red filter causes high density in negative leading to low density in the positive -- in turn modulates transmitted light, with the filters still in place, to reconstruct a full-colour image.
