Processing Instructions
for Black and White Film
In the processing of film, the greatest care must be
observed during each step of the developing process. The exposed film must
be loaded in the developing tank in TOTAL DARKNESS. the tank lid is to be
removed only after fixing is complete.
|
1.
|
Pre-soak
|
|
1 minute pre-soak with water, 30 seconds
agitation. Make sure the water is at the same temperature as the
developer solution. Make sure that you tap the tank to release the
air bubbles.
|
|

|
Development
(Dilute D76 1:1, you must do this yourself)
~~~~~~
* Agitation
|
|
Refer to the Time and Temperature chart on the
wall or use time and temperature from film box.. *Agitate
immediately for the first 30 seconds, then 5 seconds every 30
seconds for every minute thereafter. Make sure that you tap the tank
to release air bubbles. Discard developer after using. The film is
still light sensitive. Leave it on the reel. Do not open the tank.
|
|
3.
|
Stop Bath
|
|
30 seconds with constant agitation. Discard stop
after using. The film is still light sensitive. Leave it on the
reel. Do not open the tank.
|
|
4.
|
Fixing Bath
|
|
7 minutes fixing time. Agitation should be 30 seconds for the first minute and
10 seconds per minute thereafter. Save the Fixer.
(If hypo is cold or weak, it will not clear the anti-halation
backing. Negatives will look milky. You need to fix until clear).
Save the Hypo. Return the Fixer (Hypo) to the supply vat
where you acquired it. Open tank and leave the film on the reel.

5.
|
Wash
|
|
Wash for 5 - 15 minutes. Leave film on reel.
|
|
6.
|
Photoflo
|
|
3 drops of Photoflo per 1/2 gallon of water. 30
seconds gentle agitation. (Be sure Photoflo is thoroughly but gently
mixed in water. Vigorous agitation will cause too much foam).
discard after use. You can take the film off the reel at this stage.
|
|
7.
|
Kimwipes Film
|
|
Use Kimwipes to gently dry film. Do not dry the
emulsion side! I advise against using a squeegee to dry film as it
may cause scratches on the film surface.
|
|
8.
|
Dry Film
|
|
Hang in dryer with clip at top and bottom of
film. Be careful your film does not touch other film in dryer.
Damage may result to both films. Time of drying will depend on the
number of films in cabinet at that time.
|
-
Always make sure developing tanks are full (8
oz., 16 oz., etc.) or agitation will not give predictable results.
(If one reel is used in double tank, add empty reel and fill tank to
capacity).
-
Be sure to completely invert developing tank
during agitation.
-
Agitation must be standardized, i.e., use same
procedure each time for predictable results.
