134 MOTION PICTURE HANDBOOK Miscellaneous. THE STEREOPTICON. Song slides should be thoroughly cleaned before they are used. The mark of a dirty finger is not at all decorative. The audience is not at all interested in the "whorls" of your fingers. In using a single lamp it is essential that you handle the carrier gently when taking out and putting in slides. Shomehow a brick house don't look exactly natural dancing up and down, or at least I never thought it did. The least movement of the carrier is magnified many times on the curtain. The stereo picture should be brilliant and should be clear all over. Many operators persistently allow Iheir stereo pictures to have yellow corners. With a very long focus lens, or one of too small diameter, this is not always to be avoided. But aside from these circumstances there is no excuse for such a condition. An excellent colored flood to be used with the stereo may be made as follows: Take an old reel and remove the hub. Next drill three small holes equidistant from each other around the circum- ference of the two reel sides, making the holes match so that the two sides may be bolted together. Next cover all the holes but one in one of the sides with colored gelatin paper. Lay the other side on and clamp the two together with small stove-bolts. Now affix the hub to one side and attach the whole to a suitable standard so that it will re- volve freely before, and close to, the stereo projection lens. One hole must be left open so that when it is before the lens the picture can be projected through or white light may be thrown. Another wheel like the one just described may be added, thus giving a considerable range of colors. Every operator should provide himself with plenty of spot slides made from ordinary tin or stovepipe metal. The easiest way to cut them out is to cut the spot pattern from paper and paste it on the metal. You can then cut out the pattern with a file accurately. Glass slides are not good for
