leaf shutter
Quick Summary
In photography, a shutter is a device that controls the amount of light reaching the film or image sensor. The leaf shutter, located within or behind the lens, uses overlapping blades that open and close. This type of shutter typically offers exposure times ranging from one second to 1/500th of a second, controlled by springs, electromagnets, or electronic circuits, often linked to a light-metering system. This contrasts with the focal-plane shutter, which is positioned directly in front of the image plane and uses moving blinds to create a slit that sweeps across the film.123
