Techniscope is a process for the photography of motion pictures for theatrical or television presentation designed to cut negative raw stock and developing cost in half. The process was conceived and developed at Technicolor Italiana by Dr. Giulio C. Monteleoni and Mr. Giovanni Ventimiglia. The picture information is recorded on 35mm negative using the standard Movietone width and two-perforations of height. In addition to the cost savings represented by this reduced negative raw stock usage, certain quality advantages are also inherent in the system. Techniscope photography is carried on with normal spherical lenses, i.e., no squeeze is employed during photography. Most of the “scope” systems in use produce some distortion. The earlier systems used for scope photography were quite unsatisfactory for close-ups because a change in object distance produced a change in squeeze ratio. Since the pictures are projected with a constant squeeze ratio, the effect on close-ups was to make actors' faces fat or, in profile, to give them long noses. Techniscope does not produce such distortion.
