Answer:
Materials and equipment:
Developing tank and reel
Bottle opener
Graduates or measuring cups
Thermometer
Timer
Clothespins
Squeegee
Black & white film developer
Stop bath
Fixer
Hypo clearing agent
Wetting agent
Steps:
1. Load the film into the tank
2. Mix your chemicals and get them to the correct temperature
3. Fill the tank with water. Agitate it continuously for 60 seconds. Dump it out.
4. Fill the tank with developer. Agitate continuously for 30 seconds then 5 seconds every 30. Leave it in the tank for the recommended time. Empty the tank.
5. Fill the tank with water. Agitate continuously for 60 seconds. Dump it out.
6. Fill the tank with stop bath. Agitate continuously for 60 seconds and dump.
7. Fill the tank with fixer. This one you have a choice on...some people agitate 5 seconds every 30, some 5 every 60, some people don't agitate. I agitate continuously. Dump the tank at the end of the step.
8. Fill the tank with water, agitate and dump.
9. Fill the tank with hypo clear, agitate for a minute and dump.
10. Wash the film for ten minutes, or whatever the hypo clear says to.
11. Put wetting agent in the tank, agitate for a minute and dump.
12. Take the film off the reel. Wipe it off, hang it up to dry.
What to do with the chemicals? I like developers like Neofin Blue that are used once--those you can safely dump down the sink if your local laws allow it. Stop bath is just vinegar, and you can pour it down the sink. Wetting agent is dish soap or very close to it, and it can be dumped. Fixer has to be saved--the silver in it pollutes and kills marine life. Fixer is also reusable. A good test regimen relies on pieces of expired film. Cut up a roll of old film into little hunks. Throw one in the fix when you make it, and time how long it takes to clear the film. When it takes twice as long, the fixer is used up.
