MAKE magazine 09 is out, with my article on building this panoramic pinhole camera.
I'm officially "fringe technology" now, woowoo!
My old Flickr contacts might recognize this camera as a very cleaned-up version of this prototype. Optically the two cameras are identical (can you say "optically" about something that has no optics?) and sample photos from both are tagged pin-o-rama.
If you're new to pinhole cameras in general, there's a huge amount of information on the web: I recommend the nice folks at f295.org/ and the very helpful camera-design calculators at Mr. Pinhole; and Flickr's own homemade pinhole group.
See some of my other homebrew pinhole camera designs here.
EDIT: If you're coming here from the magazine, sorry about the references to "120mm" film throughout the article. That was mistake added during editing. "120" is an arbitrary film size designation from Kodak (dating from 1901!). Its actual width is about 63mm.
