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.
Pinhole camera. Light enters a dark box through a small hole and creates an inverted image on the wall opposite the hole. Items portrayed in this file depicts.
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.
Ess was known primarily for her large-scale ambient and shadowy photographs that were often made with a pinhole camera. They usually were printed with just one earthy color, such as amber, or muted blue-black. They are shown internationally in solo and group exhibitions and reviewed extensively. Her images are intentionally left vague and ...

When two cameras view a 3D scene from two distinct positions, there are a number of geometric relations between the 3D points and their projections onto the 2D images that lead to constraints between the image points. These relations are derived based on the assumption that the cameras can be approximated by the pinhole camera model.

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.
