SETT OCH ANORDNING FOR REGLERING AV STENGNINGSRORELSEN HOS EN KAMERASLUTARE

摘要

A process for controlling the closure of a diaphragm includes measuring the light intensity with the diaphragm fully open and memorizing a value related to the correct diaphragm opening. The diaphragm is then progressively closed while sensing the intantaneous light value. The memorized and instantaneous values are compared to determined proper diaphragm opening.
