Abstract: In the development of color camera matching techniques it was found inadvisable to use colored paper or other opaque material illuminated by direct front projection. The reasons are: (1) illumination of the test chart is extremely critical in obtaining the exact values of each color chip on a day-to-day basis; and (2) generally, stable color papers do not have the degree of reproducibility in manufacture and the degree of saturation required for precise measurement purposes. A color camera alignment and matching technique has been developed using 8 × 10 transparent slides of both black-and-white and color. This technique required that the source of illumination for the slides be of the proper brightness and spectral response normally encountered on a live set.
