To develop film:

1) Follow the kit instructions for mixing the chemicals, and label the datatainers. Chemicals can be mixed and stored ahead of time. Make sure to squeeze any air out of the top of the datatainers, to help preserve the chemicals. All the chemicals, including the bleach, can be reused for up to 10 rolls of film or more (maybe only 3 rolls if using the b&w kit to develop Kodachrome).

2) Place the datatainers in the large tray and fill the tray with water that is hotter than the temperature range that the kit prescribes for the chemicals. After a few minutes, test the temperature of the chemicals, and make any adjustments to the water in the tray so that it brings the chemicals to the right temperature.

3) Gather your materials, particularily the hammer, Super 8 cartridge(s), and developing tank. You won't need the reel holder inside the tank, just the tank and its lid.

4) Make your space light tight and turn off the lights. Let your eyes adjust, and look for light leaks. Fix any before proceeding.

5) For Super 8: In total darkness, hold the Super 8 cartridge on an angle against a hard surface so that the edge of one side rests on the surface.

Strike the cartridge with the hammer on its upturned edge. You may need to strike it 3 or more times to crack it. Then pry open the cartridge and locate the spool of film inside.

Remove and completely unravel the spool of film, remove it from the core, briefly rinse it (optional - facilitates solution flow), bunch it up, and stuff it into the developing tank. Put the lid on the tank securely, and then turn on the lights. (Now that you don't need the room to be light tight, you can open the door and window to improve ventilation.)

For 16mm: In total darkness, simply pull the film off the 100-foot daylight spool. Keep in mind that you only need to spool off as much as you feel is appropriate for the tank you’re using, then return the rest to its light-tight box. You can keep track by estimating an arm’s length of film as equal to about 3 feet. Be careful with 400-foot loads because they have nothing more than one small plastic core to support them.

6) Follow kit instructions for processing. The times the kit gives are for from the time the chemical is first poured into the tank until the time that the next chemical is poured. Use the funnel to put the chemicals back into the datatainers. When developing b&w film, follow the fix with a few minutes of Hypoclear, which will cut the rinse time down to 4 minutes.

7) After rinsing, hang the film up on a line or shower rod and blow dry.

8) When dry, find the tail end of the film, which will read "exposed." Spool the film onto a reel (the sprocket holes are closest to you when spooling from underneath the reel left to right).
