Abstract: Observer reactions are the final criteria in determining if a color photograph adequately reproduces a scene. These reactions indicate that ordinary colorimetric measurements cannot serve as the sole indication of reproduction quality. Dependence of the state of observer eye adaptation on viewing conditions has been found to overshadow simple colorimetric considerations. Adaptation requirements in color photography have been met through application of the so-called “first and second black conditions.” It will be found essential also in color television that the two black conditions be applied. In both color photography and color television, particularly the latter, a new interpretation of the two black conditions should further improve the color quality of reproduced scenes.
