About pinhole


	Pinhole photography is lensless imaging. The camera can be simple-a box with a tiny hole in one side, tape to act as a shutter, and a support to steady the box during long exposures. Most light sensitive material, paper or film, can be used in a pinhole camera and the resulting negative contact printed or enlarged. The ancestor of the pinhole camera is the camera obscura, a device used by early scientists to explore optical phenomena and by artists to study perspective. In the16th century, lenses to brighten and sharpen images were placed in camera obscuras. Modern photography was born in1839 when the ability to chemically fix an image in a camera obscura was perfected. Beginning with the early days of photography, some artists have chosen the pinhole system for creative expression.
