For some time now I have experimented with alternatives to a conventional, environmentally harmful developer. And I've stumbled over CAFFENOL, a black-and-white negative developer for film and photo.
CAFFENOL consists of instant coffee, vitamin C powder and washing soda. All three you can easily buy at at Aldi, Lidl, Rossmann etc. Better buy the cheapest coffees, it's all about the caffeic acid in it: bad for the stomach, essential for developing! The soup can be flushed into the toilet after one-time use.
And how and why does ist work?
Coffee contains phenols, the small sisters of Hydrochinone, the main ingredient of many black-and-white developers.
Phenols are found in various plants and foods: coffee, tea, red wine, potatoes, black currant, mushrooms, vanilla, whiskey, tree bark, various flower blossoms ...
So I mix the above plants and drinks (raw potatoes, make blossom tea, chop and cook green leaves and herbs) and mix (important!) vitamin c powder (contrast enhancer, grain cleaner and light clarifier) and washing soda ).
The results are just as good as conventional developers, since nothing is greasy, limp or brownish, on the contrary: I'm always amazed how nicely the soups work: rich in nuances and good contrasts. Plus it smells interesting, a bit like in an alchemist brewery: stirring the brew, sniffing, murmuring spells.
