camera
A device for forming and recording images; the basic tool of photography. In its simplest form, a camera is a lighttight box in which an image is formed through a pinhole or lens at one end onto a light-sensitive material at the opposite end. Most cameras contain an aperture and shutter for controlling the amount of light reaching the light-sensitive material (exposure). The recording material may be a photosensitive silver halide emulsion film, an electronic device such as a charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) sensor, or some other photosensitive material designed for a specific purpose.
