An autoexposure mode in which the aperture is selected and the exposure system selects the appropriate shutter speed for a correct exposure. Sometimes referred to as AV or simply A on exposure mode controls.

Autoexposure systems wherein the photographer selects the aperture and the camera selects the appropriate shutter speed.  

Autoexposure systems wherein the photographer selects the aperture and the camera selects the appropriate shutter speed.

Aperture Priority is a semi-automatic setting for your camera, in which you manually set the aperture (or f-stop) and the camera's computer determines exposure by selecting the shutter speed that works best for the selected f-stop. Aperture Priority mode gives you greater control over an image's depth of field in an automatic mode.

The user can manually set the aperture while the camera selects a suitable shutter speed for correct exposure. Aperture Priority is useful for many photographic situations such as determining the depth of field for landscape photography. Barrel Distortion

This is a mode where the user sets the aperture and the camera decides the shutter speed. User controls depth of field, while the camera makes a smart, corresponding choice for shutter speed based on the user’s decision. This is a common mode to shoot at underwater without an external strobe and using the EV +/- to determine the exposure of the ima [..]

A metering mode that allows the photographer to set a desired f-stop, thus allowing the camera to automatically set the appropriate shutter speed for the scene.
