Harmony Recipe  Josh Harmon was kind enough to share his
caffenol recipe and sent me two nice pictures, developed in
caffenol. They show how flexible caffenol is, and that there is
enough room for experiments. The films he tried are Arista EDU
100 (fomapan 100) and an old TMAX 100:  Locked Gate, Arista EDU
100  Pinole Car Show, TMAX 100  He was out of  photo-flo and
tried using an ethyl alcohol and water mix, which did not work.
The Arista EDU shots are good though.  Here is his recipe
together with his instructions:  20oz Water (Tap is ok) 6.25 tsp
Na2CO3 (Washing Soda) 10 tsp Instant Coffee (Must be regular)
1. Pour 2 glasses with 10oz of water each, while stirring
dissolve the washing soda in one and the coffee and vitamin C in
the other.   2. Load film in tank.   3. Mix the 2 glasses
together, it should be a dark brown color and smell odd, then
take the temperature.   4. Pour into developing tank and
continue normally as if it was normal developer.   5. Fix and
dry   6. Your Done!  Arista EDU 100:  7-8
