Meaning of Camera

Chapter Three

Camera is a device for recording an image of an object on a light-sensitive surface. It is essentially a light – tight box with an opening (Aperture) to admit light focused onto a sensitized film or plate. All cameras have included five crucial components

a. The camera box, which holds and protects the sensitive film from all light except that entering through the lens

b. Film or CCD , on which the image is recorded

 c. The light control , consisting of an aperture or 

 diaphragm and shutter, both often adjustable

d. The lens, which focuses the light rays from the subject onto the film, creating the image

e. The viewing system,  which may

be separate from the lens system (usually above it) or may operate through it by means of a mirror.

Camera obscura

The camera was inspired by the camera obscura a dark enclosure with an aperture (usually provided with a lens) through which light enters to from an image of outside objects on the opposite surface and was developed by Nicephore Niepce and L.J.M Daguerre in the early 19^th century .
