Abstract
In comparing the color quality of motion picture projector light sources, it is of little value to judge bare screen colors, with no film in the gate. A complete specification of the spectral distribution of the radiant energy is required. Short-cut methods of evaluating and specifying this important property are described, involving the use of red, green, and blue filters to determine the ICI trichromatic coefficients, and, from these, the color temperature. A method of combining direct color measurements on the carbon arc crater from various angles of view to yield the screen color in any optical system of interest is also described.
