American cinematographer (Jan-Dec 1926)

Twenty AMERICAN CINEMATOGRAPHER September. 1926 hazard. Exhaustive experiments and research have proven conclusively that the best splices cannot be made by hand. First: It must be narrow enought in width to conform to the perriphery of the sprocket wheels. Second: It must be uniformly scraped. Third: Perforations must be in perfect register. Fourth : Cement must be quickly and evenly applied. Fifth : Uniform pressure must be quickly applied. The answer to this is, to properly splice film, it must be done automatically. It certainly is the duty of exchanges to properly inspect and splice the film served to the theatres. It is also the duty of the projectionist to make as good splices as possible, and a little more thought and pains on the part of the projectionist in making splices will greatly add to the life of the film and react in better service from the exchanges. The Famous Players-Lasky Corporation, as well as this writer, is ready and willing at all times to co-operate with the projectionist for improvement in projection and the eradication of film damage.

New Condensers Made From Heat-Proof Optical Glass Details of the manufacture of "S. O. G. Condensers" were divulged this month by the Fish-Schurman Corporation, agents for the condensers. The product is made from an optical and heat-resisting glass, known as "Ignal" glass, which has a low co-efficient of expansion, .0000040 between 32 and 320 degrees F. While the usual run of optical condensers withstand changes to temperature to 120 degrees F., this form of glass is impervious to changes to 350 degrees and more, it is said. Helping you to "get it on film" GET it down on paper ! " is the slogan of the business man — and the poet. With directors and cameramen, the phrase becomes "Get it down on film!" And "the Coops" help you to do that. For under their constant, uniform, dependable light cameramen can take each scene at its very best. Any lighting problem we can work out for you?
