Pinhole Polaroid Project

For World Pinhole Day I modified a Polaroid Land 330 to have a foil pinhole which is 0.32mm or f/156. It was quite easy to remove the Polaroid shutter assembly and install the pinhole. I didn't think it would even work but my calculations were correct and even the first frame was properly exposed. Exposure times ranged from 1 second to 2 minutes.
