Photography and Photographers Information

Photography is the science of producing permanent images by recording light or other form of radiant energy onto a light-sensitive surface, such as photographic film or a silver halide emulsion or even an electronic media.  Photography is also an art, as it requires a person’s control, precision, and selective eye to create a good picture. It plays many important roles in today’s society. It is used in magazines, newspapers, advertising, military, and many more to record and display captured moments or project images.

The term photography is a combination of two Greek words: photo, which means light, and graph, which means drawing. To take a photograph, therefore, is to “draw with light”. But where a painter uses brush to draw an object, a photographer uses a camera.  

A camera, the photographer’s main tool, is a device that forms images. It consists of 6 basic parts: lens, shutter, focusing mechanism, viewfinder, adjustable aperture, flash, and body. All parts are interrelated. To create a photographic image, a photographer controls the camera to manipulate the amount of light the recording material (e.g. film) is exposed to relative to the amount of light required to form an image.

Capturing an image is only one part of the process of creating a photograph. The second part involves the rendering of captured latent image into a visual image by printing the developed film negative onto a paper. Images produced by digital cameras, on the other hand, are uploaded to a computer or photo-sharing site.  Different cameras have different functions. As such, a familiarity with a camera’s specific functions is emphasized to produce superior photographs.
