Home Movies (1945)

HOME MOVIES FOR JULY PACE 299 On the shelf, but not shown in diagram, are guides to hold the piece of cut film in place centered with the projected image of the movie film. The area within the guides is painted flat white in order to provide a miniature screen on which to project the film in selecting and focussing the frame to be enlarged. Immediately below the film holder and transport is the enlarging lens and holder. Your projector lens may be borrowed for the purpose. A small wooden cleat with a hole bored in center to take the lens, holds it at required distance from film to project the image on the cut film below. Hole should be a tight fit — preferably made large and finished with a strip of cork or felt — in order to provide a snug fit and consequently easy adjustment and focussing of the lens. Obviously, actual exposure of the piece of cut film must be made in total darkness, or with safelight illumination where ortho film is used. The easiest method is to line up the frame to be enlarged by projecting it in a darkened room on the miniature screen, then turn off the light long enough to insert a piece of cut film. With the film in place, turn the enlarger lamp on, exposing the film for the required interval. Then, extinguishing the enlarger lamp, transfer the exposed film to a light-tight box or paper safe provided for the purpose, there to be held until ready for developing and printing. The interval of exposure will have to be determined by trial and error. However, the following facts will serve as a basis to start from. Using the lens from my Revere 8mm. film projector, I reduced size of opening, in order to increase sharpness of image, by placing over front of lens a single orifice diaphragm made from a pop bottle cap as shown in diagram B. Opening in this cap is exactly J/8" in diameter. A snug fit of cap over lens was provided by building up edges of cap with scotch tape as shown in the detail figure, diagram B. With film shelf adjusted to a distance of approximately 8" from front of lens, I allow an exposure of 8 seconds by counting the familiar "one-thousandand-one, one-thousand-and-two," etc., using 2%" x iYA" Eastman contrast process ortho cut film. Just as in photography, the Weston speed of the cut film will determine the amount of exposure to be given in making the enlargement. As the "trial and error" method is the only dependable one by which to arrive at the amount of exposure, it follows that once an exposure figure has been established, the same film should be used thereafter. The exposure required for Kodachrome frame enlargements will be longer than that required for black and COLOR Seashores in the days just ahead, will be more than yellow sand. Motley crowds . . . vivid bathing suits . . . gaudy-striped umbrellas .. . sailing regattas, motor boats . . . here's a pictorial kaleidoscope for the color photographer. Be sure to depend on your WESTON Exposuremeter for brilliant, fulltoned pictures. The MASTER'S exclusive exposure-control dial, used with the brightness-range method, assures faithful rendering of colors. And by its highly selective viewing angle you'll escape the sooty shadows and lifeless highlights so common in seashore photos.
