I developed a Black and White film with Coca Cola... and it works !
Caffenol or developing a film in coffee is a well known thing. But what about Coca Cola ? Well, it worked.
The recipe :
Coca Cola (the normal one), 300 ml
Soda Ash : 30 Grams
Vitamin C : 1g (one tablet)
Sodium Bicarbonate : 5g
A few rotations of the tank every now and then, and the film was left to process for 60 minutes.
Fixing was the usual method.
