84 PRACTICAL CINEMATOGRAPHY be mounted upon the bench within the dark room, so that the operator can work in a lighted apartment. In this arrangement, however, the camera should be clamped firmly to a rigid foundation, so that it may not move during exposure. This also ensures that the light should remain at a constant distance from the machine. This camera can be adjusted easily and cheaply for the purpose of daylight printing. All that is required is a square funnel, about two feet in length, made of wood and so designed that the smaller open end fits into the front recess of the camera after the shutter panel is removed or opened. This funnel should be made after the manner of a Kodak enlarger, and blackened on the inside, with a dull medium, so that no reflections of light are set up. When this funnel is attached it is only necessary to stand the camera on its rear face so that the opening of the funnel points directly to the clear sky overhead, not towards the sun, and to turn the handle upon the one turn one picture gear. The printing speed will vary with the intensity of the light and the density of the film. Obviously the camera can be run more rapidly on a bright summer than on a dull winter day. In the first case it is safe to turn the handle as fast as possible, but in the second the speed would need to be about one picture, or handle turn, per second.
