We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

sified than is now possible. All dramatic action, in fact, will be powerfully heightened, by that same illusion of reality. In the Spoor-Berggren system, according to the inventors, the picture starts with the screen and extends into the background. The picture retains the real, natural perspective of all objects photographed, because a camera focus approximating that of the human eye is contained in the special lens system. The new camera captures two images and resolves them into a single picture on a special width film, bringing to the negative the full relative shadow values of the photographed object. Optically, the projected picture permits the spectator's eye to see with natural vision what the special lens system (in effect an eye itselfy sees in photographing the scene. The new lens system gives a widely increased angle of vision over the scene being « shot », thereby permitting close-up views of groups instead of individuals. Thus, the facial expressions of a number of persons may be noted simultaneously where, heretofore, in standard motion picture work the camera has been forced by its restricted angle of vision to concentrate on individuals. The importance of this element to the filming of stage plays and musical comedy is very great, allowing full-stage action to be photographed in one picture with complete detail of the players 'actions and expressions. No longer need motion picture audiences feel « blinders » being applied to their vision as the picture fades into an individual close-up. Now all characters stand out in their full pictorial values as the eye sees them in a stage play, permitting observation of every bit of action on the stage at the moment. In explaining the relation of the lens system to the eye it was stated that the double perspective or image action of the eye was eliminated, retain, ing only the double angle shadow effect which in normal vision gives objects their three-dimensional characteristics. The human eye normally represses double perspective, except in cases where intoxication or a similar condition paralyzes automatic control of the optical system, causing the eye to see two images. In this respect, again, the new camera duplicates the human eye, except that it continually corrects for the double image, photographing only the double angle shadow. By means of this double angle shadow, motion pictures that are flat and two-dimensional, will simulate, real, three-dimensional objects with all the warmth of light and shadows which gives depth and space in normal vision. The contours, flat areas, vistas, and panoramas in the range of the Spoor-Berggren camera « eyes » will be recorded on film, as they are ; delicately shaded in curvature, or reaching back in straight lines of true perspective ; in other words, modeled, to use a sculptor's phrase, in their true physical and optical proportions as the eye sees them with normal vision. 6-ingl. ol
