arthur_gottschalk Posted April 23, 2008 Share Posted April 23, 2008 I have a very well made 4x5 pinhole-zone plate camera made by the Photo Technical Group some years back. Unfortunately I've misplaced the documentation/ exposure calculator for this camera. I know they once had a presence on the web but I can't find them now. Can anyone help?
