This picture was taken with this camera
I made it very quickly ( less than 2 hours I think).It is an ordinary tin box.I used cardboard inside to be sure the roll film won’t move from its place. I drilled 4 holes and inserted rawlplugs for the winding system. I used two wheels of a toy car as knobs.
Ok, the axis of the film is not quite straight….
Ok, the vignetting is too strong….
OK, the pinhole is too big…
Material: tin box
Focal length: 60mm
Pinhole size: 0.3mm
