The Trashcam Project is the brainchild of four German sanitation workers and photographer Matthew Hewing, who came together for this utterly unique art project. The team installed a bunch of pinhole cameras in 1,000-liter dumpsters in some of their favorite spots in Hamburg, capturing the spirit of the city through trash. Pinhole cameras are notoriously testy devices, and sometimes getting a good shot can be extremely difficult, but we think these photographs have come out beautifully.
