Pinhole camera information


A home-made pinhole camera lens

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 size of the images depends on the distance between the object and the pinhole.

A Worldwide Pinhole Photography Day is observed on the last Sunday of April, every year.[1]
