American cinematographer (Jan-Dec 1924)

June, 1924 AMERICAN CINEMATOGRAPHER Tiventy-one formed us that it was impossible to clear out the place and the barroom was only swept out once in fifteen months." The interiors of the Davis production were made at the Mayer-Schulberg studios. Besides Davis and Heimerl, the company included Vivian Rich and Hayford Hobbs, co-stars; Milton Ross, James Williams, assistant director, and C. Glaize, technical director. CO-OPERATION OF THE TECHNICAL DEPARTMENT (Continued from page 11) behind them. And what unnecessary waste has resulted from the "over-ageing" of sets through a too liberal use of a spray gun. Should it be necessary for the technical department to be instructed as to what construction will allow shooting and what will not? Granted that they know what the action is to be, shouldn't it be a comparatively elementary matter for them to bring about construction that is photography-proof — if they really know their business? And doesn't it seem fundamental that, in order to work successfully in motion pictures, the technical department should know just what can be photographed and what cannot be photographed? If the technical department's knowledge is not specialized enough to include a recognition of all ramifications which go to make up production economy without a sacrifice to art as will appear in the finished picture, then why don't the head of the technical department consult the cinematographer as to photographic possibilities before time and money are poured into a set that must ultimately be changed because it will not allow filming? There is no excuse for the wholesale reconstruction of sets. If the technical department will not, from within itself, take cognizance of the possibilities and impossibilities of lighting and photography, then it should be wise enough to consult some one who knows, and that is the cinematographer.

Measures made with 200 watt Type C, Mazda Lamp. The lighter glasses such as Nos. 1 and 2 would be of little value in film protection, but are useful in spectacles. Nos. 3, 4, 5 and 6 would be effective in small projection machines with a thickness of 2 mm. With higher power lamps, a thickness of double that given would prove very effective, providing some means were devised to dispose of the absorbed heat. Otherwise, re-radiation would occur and the film would be heated. Another type of protection filter is a thin metallic film. Here we have both absorption and surface reflection, the relative amounts depending upon the metal used and its state. This metal must be supported by something —from India From D. L.
