In contemporary society,there is no other form of communication that moves us to the same extent as photography as an art form. It is a universal language. This subject matter had continued to evolve gaining strength from one generation to the other yet the character of this creative phenomenon is not quite perceived and appreciated. Presently, photography has acquired a new definition. This is a result of the breakthrough in digital photographic practice the most recent technological invention in contemporary photography. This process involves the use of a digital camera, a sophisticated and complex computerized machine which does not require the use of film. Images recorded are stored in a memory. Digital photography is thus a process of recording the image of an outside scene with a light–tight box with a lens and CCD (Charged Couple Device) which sensors the image in place of the film. The full–frame image captured is displayed on the LCD (Liquid Crystal Displays) or Thin Film Transistor (TFT) view screen. The LCD is a kind of electronic screen or
monitor which allows the viewing of the image that is in focus, unlike the film camera which records the image, the digital camera stores the image taken in a memory card. The memory card depending on its capacity can save far more images than is possible with a length of roll film and at higher resolution. Photography as a process thus has a powerful aesthetic value not just as a means of taking pictures but for documentation and history. The Development of photographic practice prevalent today started from a very humble beginning. In the ancient times, the artist used to be the photographer.
Types of Photography
Photography is considered as either still or motion–picture.
Still photography records single self-contained images that cover principally the recording of optical images formed by a lens in a camera and the duplication and reproduction of such images by light action to yield final pictures for various purposes. Generally, still photography is considered fewer than two categories. First, is pictorial and record photography the aim of which is to yield a more or less accurate representation of an object photographed as an end in it. The other is applied photography in which the photographic image is an intermediate stage of or serves as a tool for other processes and procedures.
Motion-picture photography otherwise known as cinematography involves the use of a continuous strip of film which records sequences of images representing successive movement or phases of a subject in motion. Suitable projection is then used to recreate the illusion of movement. With digital photography, successive movements of activity or action are stored in storable
Conclusion There have been two complementary yet distinct aesthetic approaches to photography. There has been the recognition of the basic qualities of photography and the desire to make use of them in a functional way. Photography is a potentially great creative art. It is an impersonal method of expression.
