Recent Improvements in Carbons for Motion Picture Studio ARC Lighting
Recent improvements in carbons for broadside lamps and spotlamps are described. New negative carbons, designed for use with spotlamps result in more quietly burning arcs. — New carbons have been designed for broadside lamps giving quieter burning and steadier light. The light is of the same spectral quality as that of the spotlamp-filter combinations used for Technicolor photography. Curves of spectral energy distribution of light received on the set and records illustrating the improved steadiness and quieter burning are shown.
