A camera is a device used to capture images, as still photographs or as sequences of moving images.
The size of the aperture and the brightness of the scene control the amount of light that enters the camera during a period of time.
Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of some kind of enclosed hollow, with an
aperture at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. Most cameras have a lens positioned in front of the camera's opening to gather the incoming light and to focus the
image on the recording surface. |
