Photography is the art, science, and practice of creating pictures by recording radiation on a radiation-sensitive medium, such as a photographic film, or electronic image sensors. Photography uses foremost radiation in the UV, visible and near-IR spectrum.[1] For common purposes the term light is used instead of radiation. Light reflected or emitted from objects form a real image on a light sensitive area (film or plate) or a FPA pixel array sensor by means of a pin hole or lens in a camera during a timed exposure. The result on film or plate is a latent image, which is developed into a visual image (negative or diapositive). Photography and painting are the same. Each renders imagination in tangible form. The difference is that painters can work completely from imagination, although most of us work from life as a starting point.
