I have been thinking about making a curved film plane camera using plumbers pipes. Then why not test the layout by making a Guinness-Cam.
Stage one buy a can of Guinness and drink the contents .
Most of the can cameras use paper negatives, I didn't want it that easy..
Don't like the idea of paper negatives,some modification to the can will be needed, .
The focal length would only be 65mm if the pinhole was on the outside of the can . I wanted 90-95mm , so some creative woodwork will be needed.
