The color rendering of some of the scenes is not all that could be desired, though the definition throughout is excellent. The feature of the Technicolor process is the method of preparing the final positive. The red and green images are prepared on separate films on a specially thin film and the two films are then cemented together in register. A number of two-color films prepared by the Kodachrome process have been exhibited at the Eastman theatre. An ingenious scheme of tjiree-color motion picture photography has been worked out by Berthon-Kellner-Dorian. The method consists of photographing an object through a single lens covered with Fig. 4 275
