Photography is the process of making pictures by means of the action of light. 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.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally the product of photography has been called a photograph. The term photo is an abbreviation; many people also call them pictures. In digital photography, the term image has begun to replace photograph. (The term image is traditional in geometric optics.)
Photographic image-forming devices
Most commonly a
camera or
camera obscura is the image forming device and
photographic film or a digital storage card is the recording medium, although other methods are available. For instance, the
photocopy or
xerography machine forms permanent images but uses the transfer of static
electrical charges rather than photographic film, hence the term
electrophotography. The
rayographs published by
Man Ray in
1922 are images produced by the shadows of objects cast on the photographic paper, without the use of a camera. Objects can be placed directly on the glass of a scanner to produce pictures digitally.
