Photography is the art, science and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor.The word «photography» was created from the Greek roots φωτός (phōtos), genitive of φῶς (phōs), «light»and γραφή (graphé) «representation by means of lines» or «drawing»,together meaning «drawing with light».
