Photography is defined as the technique of recording and generating permanent images by capturing light patterns reflected from objects onto a light-sensitive medium through momentary exposure using a camera. It involves both the science relating to the action of light on sensitive materials to produce pictures and the art or process of producing pictures through this action of light.

1. Definition of Photography
Photography is the technique of recording and
generating permanent images, by the capturing
and preservation of physical stimulus-patterns on
a layer of photosensitive material. It involves
recording light patterns as reflected from objects,
on to a sensitive medium through momentary
exposure. The process is done through
mechanical, chemical or digital devices commonly
known as camera.
The science which relates to the action of light on
sensitive bodies in the production of pictures.
The art or process of producing pictures by this
