摘要
A voltage-responsive diode or resistance is connected in parallel with the measuring instrument controlling the shutter opening in an automatic exposure arrangement. High voltage drops across the measuring instrument cause a low-parallel impedance, thereby decreasing the current through the measuring instrument, and thereby in turn correcting exposure errors resulting from the high-contrast lighting conditions.
