The advent of photography, from the Ancient Greek words φως phos ("light"), and γραφη graphê ("stylus", "paintbrush") or γραφω graphō (the verb, "I write/draw"), together meaning "drawing with light" or "representation by means of lines" or "drawing", has gained the interest of scientists and artists from its inception. Scientists have used photography to record and study movements, such as Eadweard Muybridge's study of human and animal locomotion (1887). Artists are equally interested in 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 used to preserve favorite memories and as a source of entertainment.
I eagerly await new concepts and processes. I believe that the electronic image will be the next major advance. Such systems will have their own inherent and inescapable structural characteristics, and the artist and functional practitioner will again strive to comprehend and control them.
JPEG (pronounced JAY-peg; IPA: [ˈdʒeɪpɛg]) is a commonly used standard method of compression for photographic images. The name JPEG stands for Joint Photographic Experts Group, the name of the joint ISO/CCITT committee which created the standard. The group was organized in 1986, issuing a standard in 1992 which was approved in 1994 as ISO 10918-1. JPEG should not be confused with MPEG, the Moving Picture Experts Group, which produces compression schemes for motion pictures.
JPEG provides for lossy compression of images (although there are variations on the standard baseline JPEG which are lossless). The file format which employs this compression is commonly also called JPEG; the most common file extension for this format is .jpg, though .jpeg, .jfif, .JPG, and .JPE are also used.
