The hole, in or near the lens, through which light rays travel onto the film or digital imaging sensor.
The aperture controls the amount of light that enters the camera and the depth of field in your photograph.
The size of the hole can be altered by a ring on the outside of the lens marked in f-stop numbers. The higher the f-stop number the smaller the hole.
Larger f-stop number = large depth of field.
Small f-stop number = small depth of field.
