Figure  11-29.—Agitating  a  small  developing  tank. (fig. 11-29). The initial agitation should be 30 seconds. Place the tank in the sink on its bottom (cover up). 4.  Once  every  minute,  agitate  the  film  for  five seconds by slowly inverting the tank end to end. After each agitation cycle, place the tank back in the sink. If the tank is held during the entire developing period, the heat  from  your  hands  may  heat  the  developer  and produce unpredictable results. 5.  When  only  10  seconds  of  developing  time remain,  remove  the  cap  from   the   tank   cover. Immediately start pouring the developer out of the tank through  the  light  trap  pouring  hole.  Dispose  of  the chemicals according to the local instructions of your imaging facility. This step should take about 10 seconds to complete. 6. When the developer has been emptied from the tank, fill the tank to overflowing with stop bath. The stop bath must be poured into the tank through the light trap pouring hole in the tank cover. Replace the cover cap. Agitate the film in the stop bath for about 30 seconds, using the end-to-end method. 7.  When  the  stop  bath  portion  of  the  process  is complete, pour the stop bath through the light trap hole in the tank cover. 8. With the tank rover still in place, pour fixer into the tank and replace the cap. Dislodge air bubbles and set the timer to the required fixing time. Start the timer 11-32 and  agitate  the  film,  using  the  same  agitation  as  the developer. 9.  When  the  prescribed  fixing  time  has  elapsed, remove the tank cover and pour the fixer from the tank back into the bottle from which it came. Never pour the fixer  into  the  sink.  The  fixer  can  be  reused  and  then saved  for  silver  recovery. 10. The film can be washed either in the tank or in a roll film washer. If the tank is used, insert a hose down through the center of the reels until it is about one-half inch from the bottom of the tank. Adjust the water (at the  same  temperature  the  film  was  processed)  so  a steady overflow is created. Wash the film for about 20 minutes. 11. While the film is washing, rinse the processing tank, tank cover and cap with clean water. Fill the tank with water (check the temperature) and add the wetting agent. After the film has been washed, place the film, still on the reels, into the wetting agent solution. Replace the tank cover and cap and agitate the film in the wetting solution  very slowly  for  one  minute. 12.   After   one   minute   in   the   wetting   solution, remove the loaded film reels from the tank (Do not save the  wetting  solution.) 13. To dry the film, attach the end of the film to a clip  in  the  drying  cabinet  (fig.  11-30).  Let  the  film unwind from the reel as you slowly lower the reel. When the film is unwound, depress the grip clip (if the reel has one) or remove the film from the core of the reel. Squeegee the film and attach a second film clip to the lower end of the film. Close the drying cabinet door and dry the film. CLEANING  UP After processing, the darkroom and all equipment must be cleaned up immediately. Rinse thoroughly all processing  equipment:  tanks,  reels,  thermometers, funnels, and soon, in clean, warm water. Place the clean equipment where it can dry before it is needed for the next  processing  project.  Always  leave  the  darkroom spotlessly clean and in good order. CONTACT PRINTING LEARNING   OBJECTIVE:   Recognize   the purpose   of   contact   printing,   identify   the required   contact   printing   equipment,   and determine   the   procedure   used   in   contact printing.
