Photography is the process, activity and art of creating still or moving pictures by recording radiation on a medium, such as a photographic film, or an electronic sensor. Light patterns reflected or emitted from objects activate a chemical or electronic sensor during a timed exposure, usually through a photographic lens in a device known as a camera that stores the resulting information chemically or electronically. Photography has many uses for business, science, art and pleasure.
