    "abstract": "The requirements of the illuminating equipment for use in studios where color motion pictures are to be made, are somewhat different than in the case of black and white work. The mercury vapor source, used so extensively in motion picture studios where black and white work is done, is practically useless for color work. The spectrum of this source is of the discontinuous or bright line type, and there are broad spectral regions in which no radiation is emitted. The satisfactory rendering of colored objects illuminated by this source is, therefore, quite hopeless.",
