<p>IMPROVEMENT OF MOTION PICTURE IMAGE QUALITY Motion picture film is photographed with standard spherical lenses, exposing in the camera the full 35mm aperture, giving in the 1.66:1 ratio a negative image area effectively 75% larger than that of the standard 1.85:1 flat wide-screen format. The frame on the ground glass is centered on the film centerline. The negative is optically printed onto anamorphic release prints employing the standard 2:1 lateral compression ratio, bypassing the problems of flat wide-screen projection, such as dim and grainy images, shallow depth of focus, and unpredictable framing. The preferred embodiment of the invention will use the 1.66:1 aspect ratio. The centerline of the print has an image offset to the standard ACADEMY*centerline, with the height of the frame on the ground glass printed to the height of the anamorphic frame, and with unused area on the top and on the sides printed with an opaque border. Similar printing can be done using as original material 35mm film photographed with the frame on the ground glass centered on the Academy centerline; 16mm film photographed in the SUPER 16* format; or high-definition videotape.</p> |
