Home Movies (Feb-Dec 1939)

most cameras and apply a coat of flat black paint with a small brush to help remedy this condition. In exposure of Positive film, the instructions given with color film by the manufacturers are equally applicable. Light subjects or Hy showing — less exposure. Dark subjects or no sky showing — more exposure. This variance will only be a matter of a half stop in either direction and a test along this line will be very helpful in obtaining even exposure throughout the whole roll. Indoors with Positive film we use the same procedure as for color film. Light your subject with flat lighting. The contrast in Positive film itself will be sufficient. Uneven lighting will produce shadows that are too dark on the shaded side of your subject and your projected picture will not be pleasing. Back lighting may, of course, be employed. In using Positive film indoors, avoid having your subjects wear white. Colored dresses and clothes will reproduce very acceptably. The first development is the most important step in Home Processing, and your finished picture is completely dependent on proper first development. Your film should be developed until it is as black on the under shiny side as on the emulsion side, and no longer, as this will tend to weaken the image and you will have poor contrast. Watch this closely, preferably with a small magnifying glass, and when your film reaches this point, remove it to your wash water and prepare for your next step. The bleaching process removes the developed negative image and is only complete when your film is transparent and you can then see your positive image by the transmitted light of your Safelight. Five minutes usually is sufficient. Then wash film in clear running water for 3 to 4 minutes. The clearing bath merely removes the stain of the bleach and is completed in five minutes. It should be followed by another wash in clear running water. While the film is in the wash, turn on the white light and leave it on for the balance of the process. A 25 watt globe 2 ft. away is sufficient for a properly exposed film. At this point, after the white light has been on for about a minute, it is a good plan to insert your finger under the film and slowly revolve the reel thus changing the position of the film on the cross rods so that any lack marks will be eliminated. These are caused by light striking the film from the back, and, of course, where the cross rods prevent the light from going through, the light does not penetrate and will cause a flashing effect JOE LORBER Fills Your Screen with SPARKLING MOVIES Clear, sharp motion pictures are easy to take on Du Pont Regular Pan.
