Czech photographer David Balihar posts instructions on constructing a camera with stiff paper.
A pinhole camera is a cardboard box with a hole punched in it that captures images on real film. Balihar publishes a PDF plan for the Dirkon paper camera (which appeared in a Czech magazine when he was a kid) that you can print out, cut and construct yourself - a neat project for kids (and adults!) interested in photography. Check out Balihar's impressive gallery of pinhole camera images for inspiration. Thanks, Mark!
