Pinhole Photography resource page.
This page is for research into pinhole photography and pinhole cameras. Not my material, but things I find interesting about this type of photography.

This is about as easy as it gets for a wooden 120 film pinhole camera.
This is a 6x7cm camera which will give 10 shots on a film, but the frame size can be adjusted to 6x6 or 6x9 if that is preferred.
