In preparation to my upcoming workshop in FFM I returned to the developer tray in my darkroom. On the menu today: 2 cents, 5 cents, 20 cents, fingertips and developer. Counting up to 10 minutes two coins were pressed with my fingertips onto the sensitive side of photographic paper directly in the developer tray.

In another experiment that will be revealed tomorrow, a copper engraving of London was exposed to sunlight for a day, and is now resting nicely wrapped and – hopefully exposing its image – in the shade of two sheets of photographic paper.
