This is where my pinholes come from. I've cut three from this (caffine free, sugar free) can to make my lens free cameras. An now I'm planning another. Inspired by Jeanne, I'm going to make an Instant pinhole camera. Pinoroid? Polarhole? Pinaroid? All I need is a Polaroid 545 back and a little snip of ali from our friend here. Anyone who'd like to donate a 545 back to the project please get in touch!
