preparing phenol tea as a base for organic developer:

Below you can see how we cooked the liquid used for the photographs exhibited. Generally speaking, the plant teas should be strained through a dish cloth and the chemicals added whilst stirring well at the same time. Organic developer is meant to be used not long after making it and to be stored in a fridge. Approximately 300 ml of developer solution is enough to develop one film, for further developing 800-1000 L are appropriate.

We made sure to use what’s local and in season for us. We didn’t harvest the entire plant, only parts of it so that it can regrow. Using vegetable leftovers from the kitchen or coffee grounds is of course possible too.

Have a look into the frugalité creative exhibition to find out more about the plants we were using. (running until september at HFG)
