Abstract

In simple terms, exposure is the act of pressing the shutter release on the camera and allowing light to fall on the film. In practice it is the result of a number of calculations and operations. The way in which light levels are calculated, the choice of aperture, shutter speed and film all have a direct effect on exposure. Correct exposure is having just the right amount of light reaching the film to give you a negative or transparency of normal density and contrast. It therefore follows that if a film does not receive sufficient light an under exposed image will result; on the other hand one that receives too much light will be over exposed. That is not to say that every image should be given correct exposure; much will depend on artistic interpretation.
