Report of the Projection Practice Committee

Among the projects under consideration by the Committee during the past six months are those of screen brightness; its desirable values and methods of measuring it; the question of using a visual test-pattern for checking screen illumination; revisions of the projection room plans; questions of projector motors and take-ups, and difficulties incident to the starting of projector motors; requirements of sound screens; and a recently initiated survey of theaters throughout the United States to determine not only existing conditions of projection, but also for the purpose of establishing a set of recommendations regarding theater structures.
