"Advertisement for Kodacolor cine film, 1929. Kodacolor cine film employed the 'lenticular' process which made use of a black and white film stock, the base of which was embossed with a very large number of minute lenses or cylidrical ribs. When exposed through the base using a camera lens fitted with a banded three-colour filter, the image was recorded as a number of colour separation elements which, after a reversal processing, could be projected through a similar lens and filter to produce the original colours."
