| | | | | Aperture, paired with a Cameras Shutter, controls Exposure (the amount of light falling on the Cameras Film or CCD). Usually the Aperture is situated in the lens, and is controlled by a dial on the lens. | | | | | | | | While the primary function of the Aperture is to control the amount of light, it is also useful for controlling 'Depth of Field'. | | | | | | |
