Space probes approaching the giant planets of Jupiter and Saturn have taken sharp and clear pictures for us to unravel the mysteries of the universe. All these are made possible by the wonders of photography.
Photography provides us with sights of deep-sea sharks, microscopic bacteria, constellations-a million light years away, ravishing beauties and our passport pictures. A person sitting at the remotest area of any part of the world can enjoy the view of any wonder of the world. Its use is wide and varied and of tremendous importance to us. Non-existence of photography in the earlier times has left us with a very bleak image of our ancestors.
In the contemporary world the practical applications of the photographic medium are legion; it is an important tool in education, medicine, commerce, criminology and the milifary. Its scientific applications include aerial mapping and surveying geology, reconnaissance, meteorology archaeology and anthropology. New techniques such as holography, a means of creating three-dimensional image in space, continue to expand the medium’s technological and creative horizons. In astronomy the Charge Coupled Device (CCD) can detect and register even a single photon of light.By the end of 20th century, digital imaging and processing and computer-based techniques had made it possible to manipulate images in many ways, creating revolutionary changes in the world of photography.
