Photography (derived from the Greek photos- for "light" and -graphos for "drawing") is the art, 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 an image sensor.[1] Typically, a lens is used 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 electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or 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 depending on 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.

Photography has many uses for business, science, manufacturing (e.g. photolithography), art, recreational purposes, and mass Contents [hide] 1 Etymology 2 History and evolution 2.1 Precursor technologies 2.2 First camera photography (1820s) 2.3 Black-and-white 2.4 Color 2.5 Digital photography 3 Camera development 4 Uses 5 Technical aspects 5.1 Camera controls 5.2 Exposure and rendering 6 Other photographic techniques 6.1 Stereoscopic 6.2 Full-spectrum, ultraviolet and infrared 6.3 "Light field photography" 6.4 Other image forming techniques 7 Future of film photography 8 Modes of production 8.1 Amateur 8.2 Commercial 8.3 Art 8.4 Science and forensics 9 Social and cultural implications 10 Law 11 See also 12 References 13 Further reading 13.1 Introduction 13.2 History 13.3 Reference works 13.4 Other books 14 External links
