Screen Illumination with Carbon Arc Motion Picture Projection Systems

R. J. Zavesky, C. J. Gertiser, W. W. Lozier

Data are reported on the amount of light that can be projected to the screen with typical present-day carbon arc projection systems. Curves are presented which enable ready determination of illumination intensities on screens of various widths. Correlation is also made between the various systems and size of screen that can be illuminated to the brightness specified by the applicable ASA Standard.
