- Wash out measuring containers using appropriate graduates for each of the chemicals.
- Determine amount of time for your film using the film chart on the wall.
- Determine how many fluid ounces your developing tank holds.
- Calculate the 1:7 ratio (1 part developer to 7 parts of water) for your particular tank.
- For example: 2 1/2 ounces of developer to 17 1/2 ounces of water for a 20 ounce tank.
- If necessary, use water in gallon jugs in refrigerator to cool down tap water, mixing together for appropriate developing temperature (68 degrees).Use accurate thermometer.
- Use temperature conversion chart if temperature is too low or high.
(Optional) Pre-wash film-fill tank with water, agitate for 30 seconds, then dump.
1) Developer-Pour developer into tank and start clock.
2) Agitate tank continuously for 30 seconds and tap tank to release air bubbles.
3) Continue processing agitating 5 seconds every 30 seconds for remaining time.
4) Dump developer into the main portion of the sink.
5) Stop Bath– Fill tank with water, agitate, dump. Repeat this step.
6) Fix-Pour in tank straight from fix container.
7) Agitate tank continuously for 30 seconds tapping tank to release air bubbles.
8) Continue processing agitating 5 seconds every 30 seconds for remaining time.
(four minuets for all films except t-max films which require 6 minuetes)
9) Test fix with Hypo Check (small white bottle; one to two drops).
If milky substance appears, fix additional two minuetes, then, pour in right portion of sink. If not, pour back into container.
10) Perma Wash-mix 1:7 ratio, agitate for 30 seconds, then 5 seconds every 30
seconds for 5 minuets total.
(Optional) Remove reels from tank and wash film for 20 minuets in water tub.
11) Photo Flo– 1:2 ratio-Pour into tank with reels, stir reels to release bubbles, soak
for 30 seconds, dump.
12) Squeegee film and hang to dry. Ten minuets in film dryer setting at # 5. Two
hours in dryer on left (no heat).
