[Concept]
English Photography Photography term is derived from the Greek the φω phos (light) and γραφι graphis (painting, drawing) or γραφη graphê, together with the meaning of the word is "light drawing".
Refers to the use of some kind of specialized equipment for image recording process, generally we use mechanical camera or digital camera photography.
Photography will sometimes be referred to as photographic, that is, the light reflected by the object during exposure of the photosensitive media.
Photography is a photography Applied Science, with the formation and development of traditional photography to the photographic optical, photographic chemicals and electronic technology based on the formation of a unique shooting system in the long-term practice.
============================
[History]
Still remain earliest a photo in the world today can be traced back to 1827 From Frenchman Joseph Nieps, hand.
============================
[Principle]
--------------
During exposure
Making photographic light through apertures (more often it is a lens group) into the cartridge, the cartridge back (relative to the light incident direction) of the imaging medium.
, The required exposure time is also different according to the difference in ability of the actual light intensity and medium photosensitive. The illumination process, the medium is photosensitive.
--------------
[Post-production]
Photographic completed, the lifetime of the image information by the medium by converting again read by the human eye. The specific methods rely on the photosensitive means and the dielectric characteristics.
For film camera, there will be fixing, the developing amplification and other chemical processes. For digital camera, requires the processor to the data calculated, and then output through the electronic equipment.
--------------
[The equipment]
In general, people use the visible light photography, the most commonly used is a camera. Different scenes and use, the camera has a lot of classification.
Comprehensive in terms of the camera must have a few basic parts to ensure that the exposure process, which includes:
Photosensitive medium, the imaging lens, the exposure time control means, the film cartridge, the storage medium.
