Movie Makers (Jan-Dec 1935)

News of the industry RUSSELL C. HOLSLAG, ACL 210 Kodachrome ■ One important further step in bringing 16mm. motion pictures nearer to recreating actuality has been made in the latest color film developed by the Eastman Kodak Company, Rochester, N. Y. Kodachrome, the new color film described in detail in the article. Presenting Kodachrome, by Dr. C. E. Kenneth Mees in this number of Movie Makers, appears on the screen entirely free from any kind of pattern, lenticular or otherwise. It is inherently colored when returned from processing, so that it may be run on any projector without attachments of any kind. Its light transmission is such that it may be projected to the same size, under the same conditions, as is black and white. The amateur will be interested chiefly in the fact that, in shooting the film, the same simplicity of operation obtains as in monochrome. The Kodachrome film is simply loaded in the camera in the ordinary way and the color subject is photographed with any fast, normal or telephoto lens and without special camera attachments. A light blue filter is provided for artificial light and a special ultra violet absorption filter is recommended for distant shots where haze is usually present. The exposure needed when shooting ordinary pictures in color with the new film is equivalent to one stop larger than that which would be used for panchromatic film under the same conditions. The resultant color image is obtained by what is known as the subtractive process. The three basic colors are separated and recorded on the film in three distinct emulsion layers, each of which is sensitive to an individual color. After development, each of these color separation negatives is reversed and then dye toned to its appropriate complementary color. As only one film is used in the process, there is no danger of overlapping or lack of registry. Processing is carried out by special machinery and involves a complicated system of operations. Fortunately for the user, all these complications are confined to the laboratory, leaving taking and showing to be performed with the same simplicity as in black and white. The three overlapping emulsions give the film no greater appreciable thickness than any other reversal stock. The processing has been worked out to a high standard of dependability and the new color medium cannot fail to achieve wide interest and popularity.

DeVry, Inc., 1111 Center Street, Chicago, 111. The outstanding feature of this new machine will be the incorporation of an intermittent sprocket, instead of the more familiar claw, to effect the step motion of the film. This sprocket will be actuated by a specially designed form of the star and cam, or Geneva movement, which is in use in practically every professional theatre pro ff . jector today. In addition, What S neW? tor the entire projector is to be designed for hard and amateur and dealer continuous use and is to he provided with an extra powerful light source. Many features of the long used 35mm. DeVry projectors will be brought to the new 16mm. model, including the special silent chain drive. The construction will be simple but held to high standards of precision. Kemco ■ -^ handy little machine for viewing, splicing, rewinding and cleaning either 16mm. or 8mm. film recently has been introduced by the Automatic Electrical Devices Company, 324 East 3rd Street, Cincinnati, Ohio. It consists of a substantial framework which rests solidly on a broad, flat base and supports the rewind attachment, film channel, illuminant and magnifying lens. This last is held in a fixed position, leaving sufficient space underneath for the film to be inserted and removed freely. The film may be moved forward or backward at will and may be cleaned by the insertion of a special cleaning pad; a bottle of fluid is supplied for film cleaning. Incorporated in the outfit is the Kemco film splicer, which works equally well on 16mm. or 8mm. film and which may be purchased separately. Flexalite ■ The mak e r s of Photo Flood-Spot offer another new lighting unit. This one accommodates two Photoflood or other standard base bulbs and the arrangement provides two straight flood units in polished aluminum reflectors, held by a firm tripod. By virtue of universal clamps, controlled by handles, the two reflectors may be set at any angle and may be placed independently for overhead, front, side or back lighting. The manufacturer is Photolites, Inc., 110 West 40th Street, New York City. Dufaycolor book ■ According to a report recently received from Willoughbys, 110 West 32nd Street, New York City, distributors of Dufaycolor film, the widespread interest in this process of natural color photography is attested by the fact that over 1100 inquiries were received after the first announcement in Movie Makers. In response to this, an interesting booklet has been prepared, giving a complete description of the preparation and working of Dufaycolor films, not only for 16mm. but for 35mm. and various sizes of roll film as well. The tremendous amount of interest that has been manifested is a definite indication that movie makers are becoming more and more color minded. Processing facilities for Dufaycolor are centered at present in New York, where the film can be handled within forty eight hours from the time it is received. It is planned, very shortly, to supplement this by establishing [Continued on page 221] Eastman Kodak Company
