Photograph

A photograph (often shortened to photo) is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography. The word "photograph" coined 1839 by Sir John Herschel and is based on the Greek φώς (phos), "light" + γραφίς (graphis), "stylus", "paintbrush" or γραφή (graphê), "representation by means of lines" or "drawing", together meaning "drawing with light".
