CAMERA

The device used for capturing or recording images through a photographic lens is called a Camera.

Cameras work with the help of light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow, with an opening (which is called the perture) at one end for light to enter, and a viewing surface for capturing the light at the other.

A lens is positioned in the front of the camera's opening which functions as the light gatherer. It also focuses the image or a part of it at the recording surface.
