What mechanism is used to control the amount of light passing through a Camera Lens?
What mechanism is used to control the amount of light passing through a camera lens?
The answer is surely "openness." I am a little surprised to see "Shutter" mentioned in many previous answers. The shutter is a mechanism that belongs to the lens and has no effect on the amount of light passes through a lens. A shutter is a mechanism of the device. This is not the goal. Controls amount of time that the film or sensor is exposed to light from the lens. – Disclosure: I am the owner of the holiday lens www.lenslenders.com Canada.
