Dirkon – Paper Pinhole Camera

Based on a project that was published in a 1970’s Czechoslovakian magazine. Fantastic project if you have kids. A downloadable, printable PDF of a paper pinhole camera that you can cut out and build, and then take pinhole pictures. Two fun projects that you can use to teach kids some skills - both the making of the camera and then opportunities to teach about film and photography. Or…you know…if you’re a just big kid, it’s fun for you as well.
