In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor. The size of the aperture is measured in F-stop. See also shutter speed.
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.
