Movie Makers (Jan-Dec 1952)

MOVIE MAKERS 309 ience here. To insure even development, agitate gently a few times each minute by raising and lowering the rack an inch or two in the solution. At the end of the required developing time, remove the rack from the developer and allow any excess developer to drain off the film and into the tank. Step 9. Rinse for 3 minutes in cool water. Step 10. Place the film in the tank containing the bleach and agitate intermittently. Temperature of the bleach is not critical, but it should be between 60° F. and 75° F. While the film is in the bleach, all the silver forming the negative will be removed, so that the film will change from black to creamy yellow in approximately 3 minutes. To insure complete bleaching, allow the film to remain in the bleach 5 minutes. Step 11. Turn on white room lights. All remaining processing may be done under ordinary room illumination, but do not expose the film to strong daylight. FULL WASHING IMPORTANT Step 12. A 5 minute wash in cool running water is next. This wash is exceedingly important, for upon it depends to a great extent the brilliance and snap of your pictures. Insufficient washing at this point will result in yellow stains, muddy highlights, and brown tones instead of the crisp blacks and whites that you desire. To insure thorough washing, place the wash tank beneath a faucet of cool running water (see Fig. 14) and adjust the flow of water into the tank so that the tank will remain full even though water is continuously draining through the two bottom drainage holes. Place the rack of film into the water and leave it there for at least 5 minutes. FIG. 17: Beginners at home processing will be wise to develop a 6 inch test strip first before a full roll. Washing times can be cut. Longer will do no harm. Be sure that the temperature of the wash water is not over 75° F. and, if possible, avoid temperatures below 60° F. Abrupt temperature changes are to be avoided also, for they are the chief cause of reticulation. Step 13. Place the film in the tank of clearing bath. Its temperature is not critical, but it should be between 60° F. and 75° F. Agitate intermittently for 5 minutes. Step 14. Give another thorough wash, following the same technique described in Step 12. RE-EXPOSURE AND REDEVELOPMENT Step 15. The film must now be exposed to white light, or "fogged," preparatory to redeveloping it to form the final positive image. Probably the room lights have already fogged the emulsion; but to be certain, slowly rotate the rack of film about four feet from a 100 watt lamp as shown in Fig. 15. Do this for 3 minutes. By exposing the film to white light you have rendered the remaining silver bromide capable of being developed. All that is now necessary to produce the final positive black and white image is to develop the film again. Step 16. Place the film in the developing tank — the same tank of developer that you used for the first developer. Develop the film until it appears jet black on both sides when inspected by reflected light. Usually 5 minutes in the developer with intermittent agitation will assure complete redevelopment. Temperature is not critical when this developer is used as a second developer. You do not have to consult the timetemperature chart; but for best results the temperature should be between 60° F. and 75° F. Step 17. Wash film for 3 minutes in running water as described in Step 12. Step 18. Place the rack of film in the fixing bath. Agitate intermittently for 5 minutes. Remove and drain briefly. Step 19. Thoroughly wash for at least 15 minutes as described in Step. 12. This last wash must be complete to insure permanence of the images. Insufficient washing here may cause the pictures to fade and turn yellow with age due to traces of the fixer remaining in the emulsion. Make it a rule to wash 15 minutes or longer in cool running water. DRYING AND SLITTING Step 20. When it comes to drying the film, the easiest method is to use a wetting agent such as Kodak Photo-Flo; this makes it possible to dry the film free of water spots without using a chamois or sponge. Simply dilute 15c.c. of Photo-Flo in one of the processing tanks filled with cool water, being sure to rinse the tank thoroughly before filling it with the wetting agent. Then Safeguard your Film.
