Since my joining BRAS I do not recall many references to this type of photography. It intrigues me, though--the direct connection to chemical changes that make the image. However, I don't know how practical pinhole cameras would be for astronomy. If one can gain an exposure of the Sun I assume the Moon shouldn't be much more difficult.

The 21 February APOD shows forty-five days of exposure with a pinhole camera, all focused on the Sun's path through the sky...
Tips and tricks, and maybe even a few samples.
