Abstract
424,906. Colour photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. Oct. 26, 1933, No. 29748. Convention date, Aug. 11. Drawings to Specification. [Class 98 (ii)] In apparatus comprising an optical system and a multicolour screen for producing images on lenticular films, the aperture of the system in the direction at right-angles to the axes of the lenticular elements is made less than F /5, the filter being of elongated form so that the effective aperture provided by its smaller dimension (at right-angles to the filter bands) has the desired value. The lenticulations preferably extend transversely across the film. Specification 416,602 is referred to.
