The Research Council Developments for Better Theater Projection
An extensive theater liaison program undertaken by the now disbanded Motion Picture Research Council stimulated several very important advancements in theater projection during the past few years: (1) a plastic drive-in screen with a gain of more than 2.5; (2) an inexpensive light meter capable of reading both incident and reflected light; (3) a liquid heat filter to reduce heat on film and lens focus drift; (4) 35mm and 70mm projector alignment films; and (5) a film-path gage and an optical alignment tool.
