Title: Camera Obscura, 19th Century
Caption: A camera obscura is an optical device that led to photography and the photographic camera. The device consists of a box or room with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside, where it is reproduced, inverted (upside-down), but with color and perspective preserved. The image can be projected onto paper, and can then be traced to produce a highly accurate representation. Such cameras were later adapted by Joseph Nicephore Niepce, Louis Daguerre and William Fox Talbot for creating the first photographs.
