The Spicer-Dufay Process of Natural Colour Kinematography


ALL modern attempts to reproduce by photography the natural colours of a subject depend upon some method of three-colour analysis. The theory that by the admixture, in various proportions, of blue-violet, green, and orange, any colour in Nature can be imitated, has been adequately borne out by practical experiment. So-called ‘two-colour’ processes must at the best be regarded as crude attempts to saddle each of two of the primaries with one-half of the third.
