R. J. Zavesky, M. R. Null, W. W. Lozier

The results of a study of the quantity and quality of radiant energy incident at the center of the film aperture with various carbon arc motion picture projection systems are reported. The effect on the spectral quality and quantity of the radiant energy of various filters used primarily to remove nonvisible energy is also discussed.
