Abstract
212,875. Barcala, R. B. March 16, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Colour kinematography.-Panchromatic films are exposed behind a shutter fitted with three colour filters, viz. :-red-orange, green and blueviolet. The negatives are developed and printed in monochrome in the ordinary manner and then projected with the aid of a shutter having colour filters complementary to those used in taking the pictures. By this means physical tinting of the film is rendered unnecessary.
