"My solargraph tin was tied to a tree. It can be seen, that it has moved from its original place with strong wind. The exposure lasted half a year and was taken down on pinhole day. Photopaper was scanned and colors inverted."
"I used a tin with a hole in its wall. Photopaper dates back to year 1989 and has lost lot of its quality. The more interesting the result is. Picture of two similar solargraph-tins is made with a digi camera with a pinhole in its camera cap."
