Abstract
216,162. Nachet, C. May 19, 1924. Colour photography.-A tri-colour camera comprises an objective A behind which are arranged a perforated mirror B, and a green, transparent reflector C, both inclined at 45‹ to the axis of the objective. The rays reflected from the mirror B pass through a red screen to a sensitive plate 5; and the rays transmitted through this mirror are partly reflected from the reflector C through a blue screen to a sensitive plate 6, and partly transmitted to a sensitive plate 7. Exposures varying from 1/10 to 1/30 of a second are made simultaneously on three plates. Specifications 199,044 and 206,820 are referred to.
