Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, 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,.
Photography is the result of combining several technical discoveries, relating to seeing an image and capturing the image. The discovery of the camera obscura (“dark chamber” in Latin) that provides an image of a scene dates back to ancient China. Greek mathematicians Aristotle and Euclid independently described a pinhole camera in the 5th and 4th centuries BCE. In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments. The Arab physicist Ibn al-Haytham (Alhazen) (965–1040) also invented a camera obscura and pinhole camera.
