A 225-Ampere Motion-Picture Studio Carbon for Use with 3200–3400 K Color Film
A 16mm Super High-Intensity Color-Modified Studio Carbon, designed for use with 3200–3400 K color film, has been developed for set lighting and process projection in motion-picture studios. No filters are needed when a set is illuminated entirely by the color-modified carbon, as proper balance can be obtained during film processing. Only a light filter is required to absorb a small amount of blue and an excess of near ultraviolet radiation to permit the use of mixed incandescent and arc light on motion-picture sets. No filtering is needed for process projection when a relay-condenser-type optical system is employed. — The color-modified carbon in the Brute lamp produces 60% more usable light than the unmodified carbon in the same lamp for use with 3200–3400 K color film, and twice as much usable light as any other motion-picture studio light source.
