Business screen magazine (1938)

TIPS FOR BETTER SHOWS 1. Screen Illumination: — Improper illumination may he due to one or more of the following causes: dusty or dirty objective or conilenser lenses; misalignment of optical system; a soiled or inefficient screen; too long a throw f(}r the light source availalile. Lenses should be cleaned before every showing with a soft cloth or Kleenex. Misalignment of optical system should be corrected by a factory expert. For most purposes the glass-beaded screen is the best. It may be washed, from time to time, with soap and water, or may be reconditioned at the factory. Wider angle lenses, although giving a larger picture, cause greater light dissipation. '2. Goou Reels Are Cheaper Than New Prints — One of the most foolish "economies" of some commercial film users is the continued use of worn or bent reels, or flimsy reels. Costly prints shoulil be protected, both in transit and during projection, by well-constructed reels, in good condition, 3, Present A V.^ried Progr.\m — Showmanship — both in slide-film and movie presentations — is a most important factor. This means a careful choice of film subjects and correlated program material. For both dealer shows antl consumer shows, be careful to select films that will appeal to the group in question. If possible, preview supplementarj' films. It is often a good policy to add a brief comedy, travelogue, or other subject to slide-film shows. 4. Check Line Voltages — Operators should check up on line voltages w-hen giving roatl shows. This is most easily done by removing a lamp from its socket and noting the reading thereon. Most amplifiers ( sound slide or motion picture) are made for operating on 50-60 cycle current. For twenty-five cycle current, a special transformer on amplifier is needed. Note also that all amplifiers must be operated on alter nating, not direct current. In the event direct current only is available, use a small converter. .3. Helping To Overcome Poor Acoustics — Acoustics of halls are by no means always uniform. Experiment with various angles for speaker. If hall is wider than it is long, two speakers should be used, their beams crossed. Empty pasteboard cartons placed behind the speaker in "barny" structures often helps greatly to overcome reverberation. G. Protect Records and Film Strips — Many a sound-slide showing has been hindered through using a scratched record or badly scratched film strip. Film slide strips should be kept in their metal containers. It is a good idea to keep records within their envelopes at all times, and separated from loose parts, needles, etc.. which might scratch or damage them. Documcntanes — (Continued jrom Page 39) realistic production is interesting. Industry, perhaps, provides the greatest chance to creative people, for they make mechanical processes seem as exciting as a car chase, by the ingenuity of their cutting, their dramatic camera angles, and the illustrative music which increases the general appeal. Britain possesses some of the loveliest and most historic backgrounds in the world and is realizing that they offer ready-made screen material gratis. Thus film will ultimately be the means of recording reality, fictional or otherwise, and from each nation there shall flow films which could not have beert made in any other nation, yet possessing world appeal. Just how important that is may be realized by pointing out that a film made in Britain is by no means a Brilisli film, if it has been produced entirely within studio walls. fiMMMMNHbtfyfiiHl JOHN R.
