But a CinemaScope picture of 2.55-to-l would fall shy of the required brightness at a width of 46 feet. Considering the borderline cases, and the fact that blackand-white pictures require more illumination than color, in this latter example (CinemaScope) it would be advisable to change to more powerful lamps. If a lower height, say 16 feet, were considered, then the smaller lamps would be suitable for all pictures. From Figure 1 you can see also that for picture heights over 18 feet, the larger lamps are definitely required in all cases. By combining these two tables, it will be possible to determine whether existing arc lamp and d.c. supply equipment will be capable of providing the required illumination for the selected picture size. Figure 1 quantities may be computed for any projection throw and can be used for guidance in all cases. When we go from a 20 to a 40-foot picture, the magnification of all details is increased four times. For that reason the mechanical effect of film motion is also aggravated tremendously; therefore projector mechanisms, lens mountings and focusing must be held to very close tolerances. It is of the utmost importance that good projection equipment be used and that it be kept always in perfect alignment and repair. WIDE-SCREEN AT DRIVE-INS {Continued from page 15) drive-in in Austin. This was to put thin, feather-edged strips of fiber glass over the seams. It is impossible to see where the material has been joined after it is painted — there is no difference in texture under projection light.” All of the new screens at Ezell drive-ins are 80 x 40 feet, and they are curved to a depth of 8^2 feet at the center, and tilted to lean 24 inches out at the top. FLUTED ALUMINUM Now in use at the Victory drive-in at Butler, Wis., in suburban Milwaukee, is the metal fluted screen developed by the Motion Picture Research Council. The Victory installation represents development of this drive-in screen since its first experimental construction at the LaMirada drivein near Norwalk, Calif. (Better Theatres for February 1954). Aluminum is now used for the surface (instead of plastic over concrete), and this is corrugated in a series of arcs, each with a maximum width {Continued on page 28 MOTION PICTURE HERALD, SEPTEMBER 4, 1954
