Caffenol-C

For those of you who will be using Caffenol-C to develop your negatives, here is the recipe when you are mixing the developer:

5 tablespoons of instant coffee (must be caffeinated)

3 tablespoons of washing soda

1 teaspoon of vitamin C

5oo mL of 68-70 degrees (Fahrenheit) water

In two SEPARATE beakers measure out 250 mL of water to the correct temperature. Mix in coffee in one and washing soda in the other. Once the instant coffee has completely dissolved mix in the vitamin C into the COFFEE mixture. Make sure that your washing soda has completely dissolved prior to adding it to your coffee mixture. Also make sure that all the micro-bubbles have dissipated from both containers before together. This will ensure that all the necessary ingredients have properly dissolved.

Processing times will vary, however, based on tests done on the Ilford Delta 100 film, developing time is roughly around 15 minutes. I usually stop with water, but remember to check that your water temperature is cold (around 68 or below) otherwise your film may fog. Fix, hypo, and wash as usual.

Good luck and I look forward to seeing your results!
