Abstract

329,438. Bernardi, A., and Raycol, Ltd. March 19, 1929. Colour kinematography. - Images in substantially natural colours are exhibited by projecting simultaneously, and in superposition on the screen, two images from negatives taken through substantially complementary filters, one being projected through a filter like to that used in taking, and the other without a filter. The images may be taken through one lens and a dividing system provided with orange and bluegreen filters, and may be arranged in opposite corners of the usual kinematograph image space as described in Specification 312,248. Projection may be effected by an ordinary kinematograph projector provided with a pair of lenses, or with one lens and with a prismatic or reflector system collecting light from the two images, an orange filter being provided for the one image; one of the two lenses may be provided with an adjustable diaphragm. Particulars of suitable filters are set out in the Specification. According to the Provisional Specification, projection may be effected through one filter of full colour and another of weak colcur.
