peratures. Both of these films can be used as negatives or with reversal processing. In England, the integral tripack Ferrania Colour, Gevacolor and Eastman Colour films have been much more widely used. The Ilford Company brought out a new black-and-white Type HPS panchromatic negative with a daylight speed of 400 Weston and a tungsten speed of 300 Weston. It has provided small-grain size and appears to be a great advancement in emulsion manufacture. The papers reported under references 44 through 54 cover many interesting developments in the use of color and black-and-white films. Color Photographic Systems Eastman color negative and positive 35mm films were extensively used in processing laboratories during 1953, The following laboratories were handling these films: Ace Laboratories, New York; Alexander Film Laboratories, Colorado Springs; Color Corp. of America, Burbank; Consolidated Film Industries, Hollywood and Fort Lee; Deluxe Laboratories, New York and Hollywood ; Lakeside Laboratories, Gary; M-G-M Laboratory, Hollywood; Pathe Laboratories, New York and Hollywood; Technicolor Motion Picture Laboratory, Hollywood; TriArt Laboratories, New York; and Warner Brothers Laboratory, Hollywood. Eastman 16mm color positive film was being used by Pathe Laboratories in New York to make reduction prints from 35mm Eastman color negative. Most laboratories were using subtractive printing methods, although the trend toward additive printing became pronounced. Ansco color negative and positive films in 35mm were being processed by the following laboratories : Consolidated Film Industries, Fort Lee; Houston Colorfilm Laboratories, Burbank ; M-G-M Laboratory, Hollywood. Ansco color film in 16mm positive was being handled at Consolidated Film Industries, Fort Lee. Du Pont 35mm color positive film was being processed by Consolidated Film Industries in Hollywood and Fort Lee. Technicolor Motion Picture Corporation supplied 35mm and 16mm prints made by the imbibition transfer process from negatives prepared in three-strip, Eastman color, Ansco color, Kodachrome and successive exposure. Color Corp. of America prepared duplitized 35mm and 16mm prints in twoarid three-color from bipack negatives and Eastman color negatives. Film-Handling Equipment The use of magnetic film for editing purposes increased steadily throughout the year both for theatrical and television use. The average film editor accepts magnetic "dailies" and uses them with a greater freedom of operation than ever before existed on photographic film. The Westrex Editer film editing machine was introduced to the industry in 1953.55 It can handle both standard and the new small-hole perforated 35mm films, film strips, motion-picture films, magnetic or photographic sound films (single or multiple), composite release prints, and for the first time makes possible the "projection viewing" of an enlarged image on a wall or screen without extra attachments. A new editing machine, Type Record, has also been built by Union of Berlin for optical and magnetic soundtracks with built-in differential gears for film displacement and loop changes. 350 May 1954 Journal of the SMPTE Vol. 62
