A camera is an optical instrument that records images that can be stored directly, transmitted to another location, or both. These images may be stillphotographs or moving images such as videos or movies. The term camera comes from the word camera obscura (Latin for "dark chamber"), an early mechanism for projecting images. The modern camera evolved from the camera obscura. The functioning of camera is very similar to the functioning of the human eye.
But whenever you pray, go into your CHAMBER, close the door (eye), and pray to your Father who is hidden. And your Father who sees from the hidden place will reward you.[Matthew 6:6]
When you close your eyes the CHAMBER is in total Darkness -camera obscura means "DARK CHAMBER" same like our eyes ...camera work with the light of the visible spectrum ...camera is optical device which create a single image of an object or sense record it on an electronic sensor or photographic film.
The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.
A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A data display, often a liquid crystal display (LCD), permits the user to view settings such as film speed, exposure, and shutter speed.
