Cameras and Photography

Digital photography uses an electronic sensor such as a charge-coupled device to record the image as a piece of electronic data rather than as chemical changes on film. Some devices, such as cell phones, now include digital photography features.

Although digital photography is not viewed by all photographers as true photography, it in fact do meet all the requirements to be called such. While there are no chemical processes, a digital camera captures a frame of whatever it happens to be pointed at, which can be viewed later.

The pictures you take with your digital camera are easy to copy from your camera to your computer so you can print them and share them with others, and, also, to back them up for safe keeping. Some digital cameras come with software that will help you copy pictures from your camera to your computer. Windows XP, however, can copy pictures to your computer without requiring additional software. Digital cameras tend to be significantly more expensive than those that use film when comparing like for like. This, however, is offset by the fact that taking photographs is effectively cost-free with a digital camera. The photographs can be taken freely then copies can be distributed over the internet free of charge. Photography has gained the interest of scientists and artists from its inception. Scientists have used photography to record and study movements, such as the study of human and animal locomotion. Artists are equally interested by these aspects but also try to explore avenues other than the photo-mechanical representation of reality, such as the pictorialist movement. Military, police and security forces use photography for surveillance, recognition and data storage. Photography is commonly used to preserve memories of favourites and as a source of entertainment. 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

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.)
