Take a coffee bath

This is not an extravagant upper class luxury. This is a way of developing film and printing using coffee and Vitamin C.

If the two images downloaded from online interest you, you should then seriously think about bathing your film and prints in coffee. Here is the formula:

Water - 8 oz
Washing Soda - 2 tsp (Sodium Carbonate)
Instant Coffee Crystals - 4 tsp

What might the result look like? Try it yourself.
