What is Pinhole Camera? A pinhole camera is a camera without a glass lens. An extremely small hole in a very thin material can focus light by confining all rays from a scene through a single point. In order to produce a reasonably clear image, the ratio of the aperture to the distance to the screen should be 1/100 or less. The shutter of a pinhole camera usually consists of a hand operated flap of some light-proof material to cover and uncover the pinhole.

A common use of a pinhole camera is to capture the movement of sunlight over a long period of time. This type of photography is called Solargraphy. Pinhole cameras require much longer exposure times than conventional cameras because of the small aperture; typical exposure times can range from 5 seconds to hours or days.
