Caffenol, a self-brewed developer based on kitchen ingredients: coffee, soda and vitamin C. Completely ecologically sound, it can simply be flushed down the drain. That not only feels better, but also it produces beautiful negatives. Most of the time. Sometimes it doesn't go quite well and that yields unexpected beauty. "Beauty is in the imperfection".

A growing number of analogue photographers around the world is working with caffenol. Therefore there is a lively exchange of recipes and methods on the web. Because not only coffee is used, also wine (wineol), beer (beerol), all kinds of vegetable juices. Everything that contains phenol. There is a lot of experimentation. Not only for developing films, but also for developing prints in the darkroom.
