Aperture

Avatar
Written by

The lens opening formed by the iris diaphragm inside the lens. This opening can change in diameter to control the amount of light reaching the camera’s sensor as a picture is taken.

The aperture diameter is expressed in f-stops; the lower the number, the larger the aperture. For instance, the aperture opening, when set to f/2.8, is larger than at f/8.
