Photography is the art, image, science and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of a image sensor. Photography is a digital methods of image capture and display processing have enabled the new technology of “light field photography”.  It is identified as a post image capture focus algorithm.Typically a lens is used in photography to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. The result in an electronic image sensor is an electronic charge at pixel level, which is processed by electronically and stored in a digital image file for subsequent display and processing. The result in a photographic emulsion is an invisible latent image, which is later chemically developed into a visible image, either negative or positive dependingon the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Phtography means drawing with light. It’s the representation by means of lines. It’s the result of combining several technical discoveries. The discovery of the camera obscure that provides an image of a scene. Photography is a hole in the cave wall will act as a pinhole camera and project a laterally reversed, upside the image on a piece of paper. It is a box with a hole in it which allows light to go through and create an image onto the piece of paper. Photography is used as painting and sculpting. Photography it a originally monochrome whether it is black and white. Some full color digital images are processed using a variety of techniques to create black and whites, and some manufactures produce a digital camera that exclusively shoot the monochrome of pictures.

 Color photography was explored in the mid of 19^th century. Autochrome, is the first commercially successful color process. Focussing control of the camera is a viewed object or the adjustment of an optical device necessary to produce a clear image. They have a different types of focal length as normal, long focus, wide angle, telephoto, macro, fisheye or zoom.

The nature of the light recording material is a resolution measured in pixels and grains of silver halide.
