Worldwide Pinhole Photography Day Workshop - 2009
For specific details about each camera, such as focal length, fstop, construction, usage, etc., you should google the camera name. In must cases there will be plenty of information and sample images. The links google give you will be more current than what I might list here.
Three things to remember when doing pinhole photography are:
(a) It ain't documentary.
(b) Film is your friend.
(c) The exposure is not complete until the film has been advanced.
Topics to pursue: solargrams, zone plates, photon sieve, pinhole sieve, double slits from casadopinhole.net
