Projection Equipment for Screening Rooms
H. J. Benham · Journal of the Society of Motion Picture Engineers · 1948
Motion picture screening rooms have many and varied uses such as for motion picture studios, film laboratories, recording studios, film exchanges, and many other applications. The material to be presented here, however, will be concerned with screening rooms which are used in motion picture studios, and those in film laboratories. In many respects, considerably more is required of the projection equipment used in such screening rooms than is required when used in other types of screening rooms, or in regular theaters.
