Pinhole Camera Working Principle - Light Path & Image Formation Explained #1951927 (License: Personal Use)

This illustration depicts the fundamental operation of a pinhole camera: two colored rays (red and cyan) originate from the top and bottom of a tree, pass through a small aperture, and cross inside the camera chamber to form an inverted image on the opposite screen. The simplicity of this setup highlights core optical principles like straight-line light travel and image inversion without lenses. The resulting image is real, reversed, and dimmer than lens-based systems.
