Definition of Photographypho·tog·ra·phy (f-tgr-f)n.1. The art or process of producing images of objects on photosensitive surfaces.2. The art, practice, or occupation of taking and printing photographs.3. A body of photographs.Definition of PHOTOGRAPHY: the art or process of producing images by the action of radiant energy and especially light on a sensitivesurface (as film or a CCD chip)Photography is the art, science and practice of creating durable images by recording light orother electromagnetic radiation, either electronically by means of an image sensor or chemically by means ofa light-sensitive material such as photographic film. Typically, a lens is used to focus the light reflected oremitted from objects into a real image on the light-sensitive surface inside a camera during atimed exposure. The result in an electronic image sensor is an electrical charge at each pixel, whichis electronically processed and stored in a digital image file for subsequent display or processing. The result ina photographic emulsion is an invisible latent image, which is later chemically developed into a visibleimage, either negative or positive depending on the purpose of the photographic material and the methodof processing. A negative image on film is traditionally used to photographically create a positive image on apaper base, known as a print, either by using an enlarger or by contact printing.Photography has many uses for business, science, manufacturing (e.g. photolithography), art, andrecreational purposes.
