Abstract: Neither the human eye nor the conventional two- and three-color meters offer sufficient spectral correlation to accurately predict the color balance for high-quality photographic color reproduction from such light sources as xenon arcs and fluorescent lamps. The problem is that the spectral sensitivity of the human eye or of existing meters does not precisely match the spectral sensitivity of the color film/motion-picture camera system. A new three-color meter was developed, the spectral sensitivity of which is precisely matched to typically important cine camera lens and film combinations. The spectral sensitivity is precisely matched to that of Eastman Color Negative Type 5254 film, as modified by the spectral transmittance of typical cine lenses; this combination also closely approximates the spectral sensitivity of many other important film and lens combinations. Split-screen photographic tests were designed to determine the correlation between meter readings and color film response. In every case, excellent correlation was obtained between the color balance indicated and the color balance obtained on color film.
