Photography will be 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. 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. The result on film is a latent image, subsequently developed into a visual image (negative or diapositive). An image on paper base is known as a print. Photography has many uses for business, science, manufacturing, art, and recreational purposes.
