CONT

The simplest mode of determining exposure with a built-in meter is a match-needle system. In this system the shutter speed is first chosen and then the aperture setting is selected by opening the aperture until a needle in the viewfinder matches the shutter speed. Also useful is an aperture preferred form of semi-automatic exposure control, in which the aperture is chosen to assure depth-of-field. The camera automatically selects the correct shutter speed.
