|A 50ml bottle can develope 10 films or more|
Caffenol Strong is to be added to a 5% solution of Sodium Carbonate with 0,5% Potassium Bromide, not included. Potassium Bromide will keep fog in acceptable limits, but it works also without it. Developping time is about 30 minutes at 20ºC or a little more. I only tested Fomapan 100 with it and I would appreciate others experience.
