The international photographer (Jan-Dec 1930)

November, 1930 The INTERNATIONAL PHOTOGRAPHER Thirteen In Notable History of Organization has been reached so recently that there has been insu....eient time to complete the final details for presentation to the society. These will be circulated to the members of the society with the minimum possible delay. Color Committee Reports The May report of the Color Committee gave a list of producers of color pictures and the systems used. At that time the Photocolor Corporation report had not been received. According' to A. G. Waddingham, technical director of the corporation, "the color camera is of special design, photographing a pair of images in conjunction with special taking filters and an optical system employing the split beam method of photographing." The negative is printed upon a specially designed optical printer which prints the two respective images in registration upon duplitized positive stock. The print is next transferred to the green processing room and receives the application of the bluegreen complementary dye on the side containing the image from the red sensation negative. The print then receives the orangered dye upon the image from the green sensation negative. Mr. Waddingham says the process is entirely adaptable for the production of sound prints in color, either by the disc method or the sound-track on film method. The company is well equipped with a thoroughly up to date laboratory, and a new sound studio is in tbe course of construction. Film Pack A specially made negative is being marketed, for use with the Film Pack system, known as red ortho front negative. This has a blue-sensitive emulsion, on the surface of which is a layer containing a red coloring matter. In making color sensation negatives bv this system, red ortho and a panchromatic negative are placed emulsion to emulsion in the camera and exposed simultaneously. The light from the lens passed through the red ortho, recording the blue end of the spectrum. The red colored layer then filters and the blue and the red end of the spectrum passing through are recorded by the panchromatic negative. The red coloring matter on the red ortho is removed from the developed, fixed and washed negative by bathing in a 3 per cent solution of hydrosulphite of soda. New Color Process A new color process is being introduced from Germany, known as the "New Color Process." It is claimed this is usable for either motion picture or stills, although in the description the method of using it for motion pictures was omitted. Color Committee Describes in Detail Various Methods of Many Laboratories — Lighting Influenced by High Intensity Successive exposures are made in a special camera fitted with tricolor filters. The color value negatives are printed on to positive films which have their respective dyes incorporated in the emulsions. The films are then developed, fixed, washed and subjected to a warm water treatment. No formulae were given. The silver images are then reduced, leaving pure dyed images, which it is claimed can be either transferred to an individual support, or the three films can be placed in register and bound. The printing is accomplished by printingthrough the celluloid side of the film. Three-Color Additive Processes In the Herault color process a three-color sector wheel is rotated in front of the camera and the contact print negative is dye tinted so that each successive group of frames is tinted one of the primary colors. The three-color positive is then prejected with a continuous projector (Continsouza-Combes). The method is said to suppress the OFFICERS RE-ELECTED BY SOCIETY OF MOTION PICTURE ENGINEERS President, J. I. Crabtree, Eastman Kodak. Secretary, J. H. Kurlander, Westinghouse Lamp. Treasurer, H. T. Cowling, Eastman Kodak. Governors, elected for first time, W. C. Kunzman, National Carbon and F. C. Badgley, Canadian Government Motion Picture Bureau. chromatic flicker when projected at 24 frames per second; only spherical lenses are used in this projector. This plan is somewhat similar to that now being suggested by Wolf-Heide. Horst System of Color In this system three pictures are taken simultaneously with three-color filters, using a prism system in the camera. In the positive each frame carries three images, each corresponding to one of the color separation images of the negative. This method is being sponsored in Great Britain by Universal Productions, Ltd. Report From Dr. Walter Clark In a report from Dr. Walter Clark, London, August, 1930, he states that "a number of color cinematography processes are being investigated in England, and a few productions are in progress utilizing some of them. Processes being studied or used in England include Pathecolor, TalkieColor, Zoechrome, Dufay, and Raycol." The Chromolinoscope In a paper entitled "The Chromolinoscope Revived," Dr. H. E. Ives has described several applications of the instrument devised by his father, F. E. Ives, in 1901. Methods of making "ridged" images and ridged film records from threecolor separation negatives are described, as well as a method of copying film containing line images. A Review A review of recent advances in color photography is published by G. Grote in the Photographische Korrespondenz, Vol. 66, p. 91, April, 1930. Keller-Dorian Method Dr. N. M. LaPorte of the Paramount Publix Corporation says "relative to our experience with the Keller-Dorian method, while our preliminary investigations show that there is considerable merit to the process, we have not made any commercial takes to date." Camera Gate for Film Pack A camera gate that holds two films in contact while at the aperture gate in a camera and suited for composite photograph and film pack color negatives has been issued in England. The gate seems specially suited for Bell & Howell cameras and is known to produce very excellent results. First Color Film "The Glorious Adventure," first of the full length, full color pictures to see the light of day, was shown some ten years after its original debut at the Filmarte Theatre, Vine Street, Hollywood, for a week beginningAugust 15, 1930. It received favorable comments from the press. Multicolor A demonstration reel colored by the Multicolor system was shown here. The negatives were made by the film pack system and most of the scenes exhibited were made under artificial light. Sennett Brevities An exhibition of work done by the Sennett Laboratories, Studio City, Calif., was shown. All the negatives are made b-" the film pack system. The aim here, according to the Sennett organization, is to produce films with good photography and the color subdued. Magnachrome Film This system gives wide film sound and color. It is an additive method with many of the old features utilized, but designed to rid itself of
