In photography, the adjustable opening that controls light entering the camera is called?

Explanation:
Controlling exposure by adjusting the size of the opening through which light enters the lens. This adjustable opening is called the aperture. Widening the aperture lets more light in, which can brighten a scene and create a shallower depth of field; narrowing it reduces light and increases depth of field. The iris is the mechanism inside the lens that changes the size of this opening, but the opening itself is called the aperture. The shutter governs how long light hits the sensor, not how large the opening is, and the lens is the overall optical assembly, not the specific opening.
