On re-focusing to get it sharp on the right-hand side the left portion was out of focus. I have not noticed this defect when showing the film at home on a smaller screen. Do you think that the use of a larger screen had anything to do with it?" Answer. — -The fault you mention is undoubtedly due to dirt in the gate of \our projector — probably an accumulation of a waxy substance on one or other of the film guides. Open the projector gate and examine it and you will probably lind that there is dirt in the guides sufficient to hold one side of the film permanently out of focus. Remove this gently with either a bone scraper or a wooden match. Do not use any hard or sharp instrument, such as a knife, as it will injure the smooth surface of the gate and scratch films in subsequent projections. The gate of the projector should be examined from time to time for dirt (see your instruction book provided with the projector). Editor's Note. — A further letter from this correspondent shows that the fault has been correctly diagnosed. Keep your Film Moist ! L. R. T. (Hyde Park) : " A four hundred foot reel of film taken the year before last was recently projected and did not seem so good as when originally shown. The picture was steady enough but it seemed difficult to keep it sharp and appeared to jump in and out of focus erratically. The film seems rather stiff and sUghtly curled. Has it deteriorated and is there any remedy, as I rather value this film ? " Answer. — Too many cine users ignore the recommendation to keep their films in a container with a moLstened pad. The non-inflammable film universally used for home cines in these days needs a certain amount of moisture to keep it pliable. If you are not using one of the circular cans containing a pad of absorbent paper which is moistened periodically soak a sheet of newspaper in water, blot off the superfluous moisture, and wrap your reel in this, afterwards enclosing the wrapped reel in a moisture-proof box or in a waterproof case or, indeed, anything else which will prevent the paper drying quickly. If the film is left like this for a day or two it will absorb the moisture from the newspaper and will become pliable again and will project as well as new with much less risk of breaking. If you liave a number of reels and do not want to go to the expense of a number of special cans, get a metal biscuit box from your grocer, pack the reels in this and keep a folded sheet of moistened blotting paper in the box, F. W. (Hendon) writes : "How can I get moonlight effects vrith my Cin§ Kodak ? ' ' Answer. — Professional moonlight effects are often obtained with panchromatic film and a red filter, which gives a violently contrasting effect, particularly darkening the sky. The film is then stained nine. .\mateur cine users can get a similar eftect by under-exposing, facing the sun, when this is behind a cloud or obscured by a tree or simUar object. Use two stops smaller than the correct stop for the light available if full exposure were required. Instead of staining the film drop a piece of blue gelatine or celluloid in front of the projection lens when showing.
