History of Photography


Derivation

The word photography derives from the Greek words phōs (genitive: phōtós): light, and gráphein:  to write.

Definition

Photography is the process of making pictures by means of the action of capturing light on a film. Light patterns reflected or emitted from objects are recorded onto a sensitive medium or storage chip through a timed exposure. The process is done through mechanical, chemical or digital devices known as cameras.
