Top 10 the most expensive photo in the world

Photography (pronounced /fәˈtɒɡrәfi/[1]) is the process, activity and art of creating still or movingpictures by recording radiation on a sensitive medium, such as a photographic film, or an electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed 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.
