Today I converted a old Agfa Clack 6×9 camera to pinhole. It has 44mm focus distance, the pinhole diameter is 0,28mm
I shot these photo’s with kodak portra 400, and developed it by my self, and scanned it with a Epson V500
How do you calculate focus-distance? mine is 75mm-distance pinhole-film but since pinhole is 0.29mm its leading to f260 and 72mm lens 32mm equiv. 58° angle-long 84mm lenghtwise. have uploaded Lochkamera(Calculator) in german to pinhole (FB) file-section. from archive.org here:
