There are oodles of links, most of which can be found by thumping 'Pinhole Photography' into a search engine.
If anyone finds a site of note, I would be grateful if you could let me know and I will have a peer.
Sadly they will lead you away from this site and into the far flung reaches of hyperspace, in which case,
tara, happy pinholing and thanks for the visit.
