"I had a cyanotype workshop when i realized that is the world pinhole day. I decided to give them a little surprise, to show them the principle to the students. So we made 2 exposures."
"the camera was made maybe 7 years ago, from a capa/foam board, it has even a tripod mount, it has a removable back and a "display/ground glass" made from tracing paper. The sizes of the removable pinholes, made from tin cans, are unknown."
