I've finished and experimented with my extended cube camera. It takes quite a long exposure due to the small aperture of the pinholes (.o16") and long focal length (5"). I can spend up to 30 minutes waiting for the film to expose. The resulting images are detailed and sharp, for pinhole photography at least. The negatives are approximately five inches square, but I plan in the end to scan and resize the best set to one inch square each. I will make stamps out of these and create a large scroll that sequences all six stamps 4096 times (the rotational variance of six squares). I think it might take some time, and definitely some money for the paper, so everything is on hold for now.
