INTERNATIONAL PROJECTIONIST Suire 410, 545 Fifth Ave. New York, N. Y. 10017 First installation of Century's Cine-Focus projector film stabilizer on Century 70mm projectors was recently made at the Warner Theatre, on Broadway, in New York City, for opening of "The Greatest Story Ever Told," Century Projector Corp. announces. Century's most recent development. Cine-Focus is reported a device to provide better control of a motion picture film as it is being projected under any conditions. Cine-Focus is a "combination of carefully engineered related film controls," Century adds, which enhances solidity and optical perfection of the picture and, by reducing to a minimum, eliminates, for all practical purposes, film flutter and focus drift. It is also said to solve the problem of breathing necessitating focus readjustments. Positive Film Control By correcting several factors causing picture depreciation, Cine-Focus is also reported to maintain strict and positive control over the film while it is being projected and to contribute to its longer life. Reduction of the tension required by the film trap shoes and maintaining positive control of the film positioning, without exerting undue mechanical pressure on the film, results in reduced sprocket hole depreciation and makes prints last longer. Cine-Focus is "especially valuable where limiting conditions are present," says Century. Included are 70mm presentations on large screens and 35mm in larger theatres and drive-ins. It is also reported particularly adaptable to 35mm projectors in smaller, second-run theatres, as an aid in using films that have been projected under circumstances which cause them to become permanently buckled and cause in and out of focus. In development of Cine-Focus. Century says its engineers have for some time been studying factors causing loss of picture quality. One of the problems confronting all projection is the tendency of the film to distort as soon as the heat from the arc lamp hits it. This distortion is reported well known and has been carefully measured and depicted in high speed photographs. Many technical papers have been written about it, and attempts to eliminate the effects have produced many patents. The film flutter problem existing during the projection cycle becomes more and more acute as the intensity of the heat of the light source increases. This increase in heat, the firm adds, has been especially marked in the past few years. Another serious factor affecting the clarity of the projected picture has been demand by theatres for higher speed, shorter focal length lenses, Century states. Higher speed lenses are used in an attempt to obtain more light on the screen (larger screens). Shorter focal length lenses are used to increase the picture size with shorter projection distances. Introduction of new developments has, also, usually been preceded by "improvements" in associated equipment— such as arc lamps, projection lenses, screens, theatre interiors, camera techniques, film and film processing (including introduction of motion pictures in color) . Each phase of these developments has created additional problems in the projectors, it is said. Larger arc lamps using higher power create heat problems. New lenses with higher "speeds" accentuate film flutter problems. Larger screens require either larger films or shorter focal length lenses. Larger films create mechanical problems. Higher gain screens create reflection problems. Higher screen illuminations create film flicker problems as well as print density problems. Use of color magnifies the problem of selecting and controlling all of the essential contributing factors outlined as well as numerous others. iP 10 International Projectionist June, 1965
