International projectionist (Jan 1963-June 1965)

Four New Film Types Introduced by Kodak At SMPTE Convention Four new tvpes of motion picture films. offering cinematographers greater range and ease under various operating conditions, were announced by Eastman Kodak Company at the convention of the Society of Motion Picture and Television Engineers. The films include a new reversal print film, an extremely fine-grain. low-speed tvpe for recording brighl daylight scenes and a high-speed, medium grain film for photographers working with available light. They are: 1 Eastman Reversal Color Print Film. Type 7387, 16mm. 2. Eastman l\ Panchromatic Negative Film, Types ~y22\ 7221. 35mm and 16mm. 3. Eastman Fine Grain Duplicating Positive Film. Types 5366 7366, 35mm and 16mm. 4. Eastman XT Panchromatic Negative Film. Tvpes 5220 7220. '>.">mm and lOmm. Advances in emulsion making and processing methods have enabled Kn dak to introduce Eastman Reversal Color Print Film, Type 7387. Superior color reproduction — especially in greens and reds, improved sharpness, somewhat finer grain and high er speed are features of this new film. In addition, this film type will be of value when reversal film prints are used for work prints or answer prints. Its reproduced qualitv closelv matches that of an Eastman Color Print on Type 7385 through a Type 7270 internegative. It's almost a full stop faster than Eastman Type 5260. and has a high quality negative-positive silver sound track much like that of Type 5269, but superior in certain respects. The new Eastman 4X Panchromatic Negative Film will permit cameramen to film in extremelv adverse lighting situations. It even can be used in places where the lighting is so low that a reading cannot be obtained with an exposure meter. For this reason 4X Panchromatic is expected to be used extensively by news and industrial photographers and for night shooting. Despite the speed of this new film — which is about tw ice the speed of the Eastman Tri-X Panchromatic Film it succeeds there is little or no increase in granularity . The third new film. Eastman Fine Grain Duplicating Positive Film. Types 5366/7366, is faster than present fine grain duplicating positive 1mkk.natio.nal Projectionist December, 1964 films and makes possible a fourfold increase in printing speed — without a resulting increase in granularity. Scene information can be placed more easily than with earlier film tvpes. The film can be processed at high temperatures, as in an Eastman Viscomat Processor using Kodak Viscomat Developer. Type III. Cinematographers will find the new black-and-white Eastman XT Panchromatic Negative Film, Types 5220 7220 of special value for ex terior motion picture work. This film provides extremely fine grain and sharpness for outside photography or lor other situations where the inherent light level is high. It has approximately one-third the speed of Eastman Plus-X Panchromatic Negative Film, Tvpes 1231 and 7231. \\ Idle the new Eastman 4X Pan will extend available speed range on the high side. Eastman XT Pan will extend the speed range on the low side. Color sensitivity and filter factors for XT Pan are about the same as those for other Eastman negative films. iP SMPTE Asks for Color TV Control M.\\ YORK — Careful control in staging and photograph) of color films for television has been recommended bv a special engineering subcommittee of the Society of Motion Picture and Television Engineers. I he joint subcommittee of the Societv"s Television and Color Committees has been working to establish >\IPTE Recommended Practices for density and contrast range of films for color television. During this work, the group reported, "it became evident that optimum control of release print density range could be achieved onlv if the original photography were carefully controlled.'" Subcommittee Chairman John M. Waner. taking note of the special problems of color television film transmission and reception, summarizes the findings as follows: • It is desirable to limit the density range of the color print, and to include a ''reference white" and "reference black" in the scene for the benefit of the video operator or automatic video control. • The recommended maximum and minimum refiectances of fully illuminated materials that are to be reproduced with good detail are 60% for whites and 3% for blacks, with existing niques. film products and tech used for special effects and night scenes. • It is emphasized that the most important, practical and effective way to control the density range of the color print is in the staging and photography, rather than in the final printing. "There is no sharp dividing line," the subcommittee reported, "between color prints that would be generally regarded as acceptable for television transmission and those that would be considered unacceptable. "The particular recommendations for color television films that are described herein represent observations taken from films with scenes that did reproduce well on a typical color television system. "Deviation from these recommendations should be accompanied with caution and should be undertaken only if a particular effect is desired or if tests show that good color television reproduction can be obtained from such films and that they can be printed and intercut properly with films that are known to transmit successfully."
