Shutter Speed Variables

The shutter speed determines how long the shutter is open, which lets light through the camera to expose the film. Shutter speed is affected by two variables: aperture and film speed(ASA). When the aperture is adjusted the amount of light passing through the lens changes. The more light the faster the shutter speed needed. The ASA is the speed of the film, a film with a high ASA will expose quickly and a film with a low ASA will expose slower. With all this data in your camera or by using a meter you can get the correct exposure on your pictures.
