"abstract": "Of the numerous factors which influence the motion picture screen reproduction of object tone values, the effect produced upon contrast by projection lens flare has received relatively little attention. Although this defect of image forming systems has been treated in texts on geometrical optics, the material is not in a form from which conclusions can readily be drawn regarding its practical effect upon image contrast. E. Goldberg1 has very carefully considered the subject of flare in photographic objectives, but since the conditions of projection are essentially different from those existing in the camera, his results are not directly applicable without modification. It is the purpose of this work to examine the relative characteristics of the motion picture positive and its projected image and to attempt a quantitative explanation of the reduction in contrast which takes place upon projection.",
