I added a pinhole camera to th eback of a cheap regular camera, allowing me to expose both sides of the film, either at te same time, or one by one. Or to just take either a regular picture or a redscale pihole picture. It needs a bit more thinking to make the doubles really work, but these first results are pretty hopeful.Taken by stratski with a Janus I loaded with Fuji Superia 200 film in Amersfoort, Netherlands. These tags describe this photo: double, pinhole, redscale, ebs, and experiment. Date: 2013-01. This photo can also be found in the album Janus - the two faced camera.
