aperture apÂ·erÂ·ture (Äp'Ér-chÉr) n. An opening, such as a hole, gap, or slit. A usually adjustable opening in an optical instrument, such as a microscope, a camera, or a telescope, that limits the amount of light passing through a lens or onto a mirror. The diameter of such an opening. The diameter of the objective of a telescope or microscope.
The best way to understand aperture is to think of it as the controls for the pupil of an eye â the wider it gets, the more light it lets in. Together, the aperture, shutter speed and ISO produce an exposure. The diameter of the aperture changes, allowing more or less light onto the sensor depending on the situation.
