Basics of Film Developing
This step, basics of film developing, is very important that can make a person
becomes a great photography. After knowing how to use the camera and how
to take the pictures, the next step is learning how to develop the film.
Although the person has a good negative; but a person doesn't have a good
develop's skill ,or doesn't know the right way about developing, how can that
person makes a good picture. He/she should know how to develop film and
how to roll the film. Basic things about how to develop the film are listed in
the book entitled, INTRODUCTORY & PUBLICATIONS PHOTOGRAPHY
written by Dr.C. Wm. Horrell and Robert A.Steffes. That is
1. Turn off all the lights in the darkroom and unwind the film. (Roll
film, except 35 mm, must be separated from the protective paper). And then
unroll the paper until the end of the film is reached which is not attached to
the paper and will, therefore, form its own roll when separated.
2. Unroll until the other end is reached, which is attached to the paper
by tape. Tear film gently from the paper when loading the film onto a reel or
into a plastic apron.
3. At this point, handle film by the edges to avoid fingerprints on the
film's picture area.
4. Fingerprints inflicted by pressure or moist fingers may show up on
the negative and in the finished print.
5. To remove the film from a 35 mm cartridge, pop off the retaining
ring with a bottle opener, allowing the roll to be removed.
6. The film is now loaded on a reel. This procedure is the best learned
by practicing with a film provided for this purpose, or an uncut, discarded
strip of negetive. Cut the leader of 35mm film square with scissors before
7. Some tanks use plastic aprons instead of reels.
8. With the reel or plastic apron now placed in the tank, and the cover
secure, turn on the lights and proceed to develop the film. needed chemicals
and equipment are pictured below.
9. Determine the temperature of the developer, then in turn determine
the time in minutes necessary to develop the film using a time-temperature
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
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
18. The fixer is then poured back into the bottle. Do not pour it into the
19. Place the tank under a cold water faucet or insert a hose into the
