Abstract: The recent advances in color photography have made more apparent than ever before the need for some simple and accurate method for the estimation of the color-temperature of light-sources. Photographers, Whether professional or amateur, are only too well aware of the influence which the quality of the illumination has on the color rendering of photographic subjects. For example, the difference in color-temperature between general-purpose tungsten filament lamps, and studio modeling lamps, or between modeling lamps and photoflood lamps, is often the. deciding factor between correct and incorrect photographic Color reproduction. In order that the photographer may easily determine the quality of lighting which he is using and make the proper adjustments to secure standard lighting conditions, an instrument that is at once compact, simple in operation, and accurate, has been developed in these laboratories. No auxiliary light-source is required for making measurements since each source is tested by means of the radiant energy which it itself emits. In this paper a discussion of the principles applied in construction of the instrument, a description of the instrument, and data showing the probable error of results are given.
