Photography

 

is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium such as photographic film or an electronic sensor during a times exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science art, and pleasure. The word photograph was coined in 1839 by Sir John Herschel and is based on greek φῶς (photos) "light" and γραφή ( graphe) "representation" by means of lines" or "drawing", together meaning "drawing with light". Traditionally, the products of photography have been called "negatives" and "photographs", commonly shortened to photos.
