Hello All, I have recently become involved in pinhole cameras and have a question that I hope someone can answer. I have a Olpe & Bussiek pinhole cardboard camera and am getting good results using b&w 400 ASA 120 film. I'd like to switch to 200 ASA infrared film with a red 25 filter taped over the shutter opening. There are many sources on the web and books that give exposure times for 200/400 b&w film but I have not seen any charts that list infrared/red filter exposure times.
If anyone knows if such an exposure table exists, I'd like you could to drop me a line; even a few hints would be appreciated .
