development chart. Set timer for recommended time.
10. Start the timer running. Then pour the developer into the tank. Tilt.
the tank slightly so that air may escape. Don't let an air-lock mislead into.
thinking the tank is full when it isn't.
11. Agitate the tank vigorously for the first 15 seconds. Then agitate.
for about 5 seconds during each 30 seconds of development thereafter.
12. After developing time has elapsed, pour developer back into the.
bottle. Do not pour it into the sink unless using a " one-shot " developer.
13. Immediately fill the tank with a short stop rinse and agitate for.
about 30 seconds to a minute. When acid rinse is omitted, the film should be.
rinsed in running water for about 30 seconds.
14. If acid rinse is to be re-used, pour it back into the bottle; otherwise,.
pour it into the sink.
15. Fill tank with fixing bath solution and agitate vigorously for about.
15 seconds. The lid may now be removed from the tank. The film should be.
left on the reel in the tank for twice the time it takes to clear the film of its.
milky appearance.
16. This illustration shows the milky appearance of a film just after it is.
placed in the fixer. The film is opaque, and all of this mildness must be.
dissolved out for proper fixation. Any hint of mildness, general or localized,.
is a positive indication the film is insufficiently fixed. If the film takes too.
much time to clear, the fixer is exhausted.
17. When properly fixed, the film is transparent and clear, as shown.
below.
18. The fixer is then poured back into the bottle. Do not pour it into the.
sink.
19. Place the tank under a cold water faucet or insert a hose into the.
center of the tank and wash for 15 or 20 minutes. If the wash water is colder.
than 65 degrees, it is advisable to treat the films in a hypo clearing agent.
before washing.
20. After the film has been thoroughly washed, place about one drop of.
a wetting agent in the tank of water. Agitate gently for about a minute. The.
wetting agent will help prevent the formation of water marks on the film and.
