  • The process of forming visible images directly or indirectly by the action of light or other forms of radiation on sensitive surfaces.
Abstract from DBPedia
    Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

    写真(しゃしん、古くは寫眞)とは、人類史上初めて登場した機械映像である。 * 狭義には、穴やレンズを通して、被写体から発される光線を再構成して実像を結ばせ、感光剤に焼きつけたのち、現像処理をして可視化したもの。このとき、感光剤に焼きつけるまでを行う機器は、基本的にカメラと呼ばれる。 * 広義には、電磁波、粒子線などによって成立する、弁別可能で存続性の高い像。 英語の "photograph" という語は、イギリスの天文学者ジョン・ハーシェルが創案した。photo-は「光の」、-graphは「かく(書く、描く)もの」「かかれたもの」という意味で、日本語で「光画」とも訳される。"photograph" から、略して「フォト」と呼ぶこともある。 日本語の「写真」という言葉は、中国語の「真を写したもの」からである。
