A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.
The Great Picture in its pinhole camera hangar. Orthorectified negative (top) and positive (bottom) representations of the photograph, partially obscured by two people. As of 2011, The Great Picture (111 feet (34 m) wide and 32 feet (9.8 m) high) holds the Guinness World Record for the largest print photograph, and the camera with which it was made holds a record for being the world's largest.

The image plane is parallel to axes X1 and X2 and is located at distance from the origin O in the negative direction of the X3 axis, where f is the focal length of the pinhole camera. A practical implementation of a pinhole camera implies that the image plane is located such that it intersects the X3 axis at coordinate -f where f > 0.
A camera obscura (pl. camerae obscurae or camera obscuras; from Latin camera obscūra 'dark chamber') [1] is the natural phenomenon in which the rays of light passing through a small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projection of the view outside.
Projection of images can occur naturally when rays of light pass through a small hole and produce an inverted image on a surface in a dark area behind the hole. This phenomenon is known as camera obscura or pinhole image. Its oldest known recorded description is found in Chinese Mohist writings dated to circa 400 BCE. [5]
The hangar-turned-camera recorded a panoramic image of what was on the other side of the door using the centuries-old principle of "camera obscura" or pinhole camera. An image of the former El Toro Marine Corps Air Station appeared upside down and flipped left to right on film after being projected through the tiny hole in the hangar's metal door.

A pinhole camera generates an image of infinite relative focus, from a point just outside the camera opening out to infinity. Lenses focus more selectively so that, for objects near the lens, the distance between lens and sensor or film is increased and is shortened for more distant objects, to a point beyond which all is in focus.
