408 B. SCHLANGER [J. S. M. P. E. areas. With the present motion picture shape, the continuity of the action portrayal of such a scene is interrupted and delayed due to the obvious limitations of size and shape. Another advantage of including the peripheral areas would be to make the spectator feel more readily the position he holds in the scene of action, as well as the sense of space. For example, the extent of peripheralvision area above, below, or to the side of the directvision area would vividly express whether the viewer is at a high point, low point, or to one side of the physical enclosure of the scene. The viewer would also be able to sense more readily the form and expanse of the surroundings of the scene of action. The director could at will "place" the spectator so as to create the best dramatic effect. Yet another advantage to be derived from the newly shaped picture utilizing peripheral vision would be the possibility of including supplementary action within the field of vision, which might be entirely separated from the principal action in a particular scene. In such an instance, the supplementary action contributes to the principal action without being disconcerting, because such action would appear less distinct than the main action. This effect obviously can not be attained with the present motion picture. Changing the shape of the motion picture directly affects the size of the screen. Of course, primarily, the size of the screen is subject to the viewing distances to be accommodated in the theater auditorium. The images and details upon the screen must not appear too small from the seats farthest from the screen. With the present average screen size, details are not sufficiently clear from the more remote seats; and if the more horizontal picture-shape were projected upon the average present screen (i. e,, maintaining the present width but reducing the height), the clarity of details and images would be still further reduced. Therefore, in order to change the shape of the motion picture, the screen would have to be increased in size. More specifically, the screen would have to be slightly greater in height and considerably greater in the horizontal dimension to offer sufficient area for both distinct-vision and peripheral-vision details of sufficient size. Enlarging the screen naturally involves increasing the width of the film to assure clear vision of the image from the seats nearest the screen. Another factor that limits the realism of the motion picture lies in the relation of the screen to the auditorium. The screen always appears small against the adjacent walls of the auditorium.
