3196. Szczepanik, J. Feb. 10. Producing coloured photographs.-In the threecolour process of producing photographs in natural colours, prints are made from the three negatives on three films each coloured with a suitable primary colour sensitive to light. The monochrome prints thus produced are superimposed and cemented together by varnish or otherwise. No coloured screens are used as in the process described in Specification No. 10,813, A.D. 1902.
