MM-10 (t r^\ PEERLESS FILM TREATMENT, sometimes known as ' vaporating," has enabled millions of prints to hold their good exhibition condition far beyond normal expectation. Extension of print life is more than ever important at this time, when shortages of raw stock have made replacements so difficult to obtain. For 14 years PEERLESS has earned the confidence of the motion picture industry as a symbol of protection. ► insist on PEERLESS FILM TREATMENT Available af laboratories, coast to coast Write for list of installations and folder, "20 Questions" PEERLESS FILM PROCESSING CORP.

Movie-THx effects Professional effects such as whirlpool, circle and sawtooth wipes can now be made part of any film in thirty seconds with Movie-Trix, a series of strips that may be superimposed upon any desired section of film. MovieTrix strips are extremely thin, will not interfere with projection, it is said, and will adhere to film permanently, though they may be removed at any time without damage. The strips are particularly useful for eliminating abrupt scene changes and providing smooth continuity. Available in both 8mm. and 16mm.. at $1.25 and $1.50, each set of Movie-Trix contains an assortment of twelve effects, including circle open, circle close, sawtooth, clock sweep, fan wipe, straight wipe, whirlpool open and whirlpool close. Movie-Trix is distributed by Willoughbys. 110 West 32nd Street. New York 1, N. Y.

Retail price of the complete meter is $32.50, the same price at which the meter was sold without the attachment, which sells separately for $2.50. Fine points of film care | Continued from page 402] is in the camera, try to complete its exposure as soon as you can, and never leave your camera lying around in the sun, even when cased. (3) Repackage, but do not reseal, exposed film and ship it on for processing as soon as convenient after exposure. If you are out of the United States, use air mail or air express. If you cannot ship your film off for processing soon after exposure, and if you must hold it under tropic conditions of heat and humidity for a month or longer, extra precautions are recommended. To begin with (as already stated in item 3 above), do not reseal any film package or can immediately after taking exposed film from the camera. This film has already absorbed an amount of moisture equal to the humidity, so that resealing will serve only to hold in this moisture unwisely. Drying can be accomplished by placing the films in a sealed can with a drying agent such as silica gel, dried rice or dried tea leaves. The drying agent should be separated from the film by a porous partition, such as blotting paper or sheets of newsprint. Handy prepared desiccating agents are the Davco Silica Gel Air Dryers, two of which will adequately dry ten 100 foot rolls of 16mm. Kodachrome. They can be obtained on order from your dealer or direct from the Davison Chemical Corporation. Baltimore 3. Md. PROTECTION AFTER PROCESSING But, by and large, many of the foregoing are problems which the majority of amateurs are likely to encounter once in a filming lifetime. It is after processing, after the film has been returned to you, that the real dangers begin — and they are largely of your own making. Scratches, fingerprints, dirt, cement stains and even torn sprockets and torn film, these are among the forms of mayhem which the unsuspecting — and usually uninformed — movie maker inflicts on his own precious footage. Here are some things to watch for: (1) Handle your films only with clean cotton gloves or. at the very least. by the edges of the film. Moist, sticky fingers leave immediately visible prints which, in turn, grow worse as they gather dirt. (2) Attach to each roll of film, immediately upon its return, leader and trailer footage well in excess of that needed to thread the film on your projector. The great majority of film scratching and damage occurs at the beginning and the end of the reel. These blank film strips are there to take this beating. (3) Clean your projector gate before every screening and clean your pictures after every projection. A habit of automatic cleaning after every editing session is especially recommended, since films pick up more dirt and emulsion scrapings there than anywhere else. It is far easier to keep your films clean than to get them so. (4) In transferring your camera footage lengths to the larger projection reels, do not overload these reels beyond the etched footage markings. Jampacked reels spill over, with consequent scratching and adherence of dirt. (5) Do not rewind your films so rapidly that they tend to slap or sway during the process. And never take up loose coils of film on a reel by pulling, or cinching, it against itself. If the coils are loose, rewind the film again. (6) After rewinding, anchor down the end of your film with some form of clip or sticker. Unanchored film soon uncoils, and any movement of the can tends to scratch one film layer against another. This is especially true with pictures in transit.
