My biggest pinhole was a 55 gallon fiber board drum that we loaded with outdated Cibachrome. Crappy color, ungodly exposure times, difficult to load, even more difficult to haul to a location. Ahhh yes, everything we love about pinhole.....
Jan, I believe you're referring to the University of California Museum of Photography (UCMP) in Riverside, where I live. Excellent place if anyone's in the area. Sevral AA prints (by him-"moonrise incl.) and some other great permanent collection pieces. New shows every couple months.

I thought that was how the original "camera obscura" and pinhole concept came about all those years ago.
It is, originally for paintings however. There is a great book called "Vermeer's camera" by Philip Steadman It has a great history of and use for the original obscura rooms. (Both portable and permanent)
Stop trying to get into my mind, There is nothing there!
Victoria Cooper & Doug Spowart also have done extensive Camera Obscura work. I spoke to them in Wellington last year, and they are completely dedicated to the medium.
They have also turned a whole room into a pinhole camera obscura for a project of theirs .One of their most notable stories is of converting a van into a large pinhole camera and then touring their home country Australia with it.
Has anyone built a LF pinhole? I have some film that is 10.5in x 120ft. I am thinking of building a 10.5x18 inch camera. My question is should I make it so the film plane at the same distance from the pinhole on a circle or flat like it would be in a normal camera. When I 've used shorter length, ~300mm, pinhole on my 8x10 the edges seem to get distorted. Was this a function of a badly made pinhole?
