Please forgive me for not being in the know, but is the really true, or is this a joke? Can you really process film and paper in coffee (with the added ingredients listed)? If so, then this is amazing -
Yes you can. The caffeic acid in the coffee develops the film, and the sodium carbonate accelerates the development. The Vitamin C is in there to act as a second developer, shortening developing times and preventing excess staining.
