Hi, Just thought I would add some images of my pinhole camera and some of the shots I have gained from it so far. The camera is made of stiff card and a cut out of a beer can for a lens. It takes a 4.5 x 3.5" negative on 5x4" paper, the paper compartment is thick enough to hold approx 25 sheets with a divider so exposed paper can be moved to the back. This is a simple design which enables me to take multiple large format pinhole images on one trip out and about using a small changing bag to move the paper to the back. The images are below are taken on Ilford Multigrade IV RC 5x4" paper, then scanned and inverted in photoshop. I will be purchasing a pack of Harman Positive when I place my next order with ag. Hopefully one day my wood work skills will improve enough for me to build an actual light tight wooden box! Hope you enjoy Jim edit: Sorry about the quality of the picture of the camera, it was taken on my old phone last year.
