Abstract
The work done in connection with the photographic effectiveness of National motion picture studio carbons has been extended to include the Sun Arc carbons and 1/2 times 12-inch Rotary Spot carbons. Energy distribution curves of the two latter types of carbon at various currents are given, and the beneficial effects of increased current upon the photographic effectiveness of these two types of light-sources are emphasized. The desirability of the higher currents in using these sources is very clearly demonstrated. Included are the effects of the use of a gelatin filter frequently used with the Sun Arcs and Rotary Spot carbons.
