History - What is Photography?
PHOTOGRAPHY.
Today, photography has become a powerful means of communication and a mode of visual expression that touches human life in many ways. For example, photography has become popular as a means of crystallizing memories. Most of the billions of photographs taken today are snapshots--casual records to document personal events such as vacations, birthdays, and weddings.
Photographs are used extensively by newspapers, magazines, books, and television to convey information and advertise products and services. Practical applications of photography are found in nearly every human endeavor from astronomy to medical diagnosis to industrial quality control. Photography extends human vision into the realm of objects that are invisible because they are too small or too distant, or events that occur too rapidly for the naked eye to detect. A camera can be used in locations too dangerous for humans. Photographs can also be objects of art that explore the human condition and provide aesthetic pleasure. For millions of people, photography is a satisfying hobby or a rewarding career.
Photography as Art
Today photography is widely recognized as a fine art. Photographs are displayed in art museums, prized by collectors, discussed by critics, and studied in art history courses. Because of the special nature of photography, however, this was not always the case. In the early days of photography some people considered the medium something of a poor relation to the older, established visual arts, such as drawing and painting. The arguments stemmed from the fact that a camera is a mechanical instrument. Because the mechanical procedure of taking a picture is automatic, detractors claimed that photography required no coordination of hand and eye and none of the manual skills essential to drawing and painting. They also argued that photography required no creativity or imagination because the photographic subject was "ready-made" and did not require manipulation or control by the photographer.A camera, no matter how many automatic features it may have, is a lifeless piece of equipment until a person uses it. It then becomes a uniquely responsive tool--an extension of the photographer's eye and mind. A photographer creates a picture by a process of selection. Photographers looking through the camera's viewfinder must decide what to include and what to exclude from the scene. They select the distance from which to take the picture and the precise angle that best suits their purpose. They select the instant in which to trip the shutter. This decision may require hours of patient waiting until the light is exactly right or it may be a split-second decision, but the photographer's sense of timing is always crucial. Photographers can expand or flatten perspective by the use of certain lenses. They can freeze motion or record it as a blur, depending on their choice of shutter speed. They can create an infinite number of lighting effects with flashes or floodlights. They can alter the tonal values or colors in a picture by their choice of film and filters. These are only a few of the controls available to a photographer when taking a picture. Later, in the darkroom, many additional choices are available.
One of the best ways to view artistic photographs is to visit museums. Today most art museums include photography exhibitions, and many have a photography department and a permanent collection of photographic prints. This is a relatively recent development. Another great way to view photographs is to look at a quality magaznie like National Geograpics.
