ABSTRACT:
A system is disclosed for automatically controlling the shutter in a camera in accordance with ambient scene light level. While the shutter is opening, incident light is weighted at only one-half the value at which it is weighted after the shutter has been fully opened. A switchable voltage divider is utilized to accomplish the weighting function in accordance with shutter blade position.
