A pinhole camera is a simple photographic device that has no lens and uses a tiny hole to project light onto a photosensitive surface, such as film or photographic paper, at the opposite end of the camera. Light passing through the small aperture forms an inverted image, capturing the scene with a unique soft-focus effect.
Pinhole cameras are often used for educational purposes, artistic experimentation, and creative photography. Their simplicity demonstrates the fundamental principles of light and optics, while the long exposure times and infinite depth of field create distinctive, dreamlike images that differ from conventional lens-based photography.
