Here are the materials you'll need:

Step 1: Create a light-tight room by closing the door and blocking any outside light. Ensure you have easy access to running water.

Arrange your tools in a way that allows you to find them in the darkness.

Step 2: Mix the developer chemical with water at a 1:3 ratio to create a stock solution. Dilute this stock solution further to create a working solution.

Step 3: Mix Acetic Acid 6% and water at a 1:3 ratio to create a working stop bath solution.

Step 4: Mix the fixer chemical with water at a 1:4 ratio to create a working fixer solution.

Step 5: Mix the hypo-clearing agent powder with water according to the provided instructions.

Step 6: Place the mixed chemicals in a jerrycan and immerse it in a large sink filled with water at degrees Celsius for 30 minutes.

Step 7: In complete darkness, open the film canister, remove the film, and load it onto the film reel inside the developing tank.

Step 8: Turn off the lights.

Step 9: Using a bottle opener, remove the bottom of the film canister and cut off the film tip. Spool the film onto the film reel, ensuring it remains light-tight.

Step 10: Place the reel inside the developing tank, pour water in, and let it stand for 1 minute. Then, pour in the working developer solution and agitate for the appropriate time based on your film type.

Step 11: Quickly pour the stop bath solution into the developing tank and agitate for 1 1/2 minutes to halt the development process.

Step 12: Fill the tank with the fixer solution and agitate for 6 minutes (4 minutes for rapid fixer).

Step 13: Unscrew the tank lid and expose the film negative to light. The film is no longer light-sensitive after fixing.

Step 14: Pour the hypo-clearing agent into the tank and agitate for 1 1/2 minutes.

Step 15: Under running water at 20 degrees Celsius, wash the film for at least 10 minutes, periodically changing the water.

Step 16: Remove the film reel from the tank, shake off excess water, and separate the reel halves. Clip the film negative and hang it to dry in a dust-free room for at least 2 hours.

Your negatives are now ready to be used for printing or scanning!
