Abstract: Three-color meters are used to measure the color quality (color temperature) of light sources, and to select the appropriate filter for balancing color films designed for one type of illuminant to light sources of a different color quality. This paper describes a direct-reading three-color meter which automatically computes and instantaneously displays both blue/red and green/red color ratio readings, independent of the absolute light level and without a need for operator adjustments. A filter computer, used to calculate color correction filters to be placed over the camera lens, is also described.
