Pinhole photography uses a small pin-sized hole instead of a lens to create images on light-sensitive film. It produces softer, low-fidelity images with almost infinite depth of field. The document provides instructions for making a simple pinhole camera from a matchbox that can take photos using standard 35mm film. Key steps include cutting a small hole in the matchbox cover to act as the "lens", loading the film, and securing cardboard "shutters" to start capturing long-exposure pinhole photographs.
