Did you ever have to make a pinhole camera for high school photography class? I did, and it looked nothing like these incredible cardboard recreations by Kiel Johnson. Aside from the strap, Johnson’s cameras are made strictly from cardboard, hot glue, and tape. His collection includes a wide variety of cameras used in the last century, and include the "ancient" 8mm, point and shoot, Polaroid, and even the latest DSLRs. Some of Johnson’s cardboard creations, like the iconic twin lens (last one), actually function as a pinhole camera. The other sculptures are not operational, but still look really cool. Check out the video below to see how he creates them.
