Aperture’s role in photography.

There are three main settings you can adjust to get the exposure you want when taking pictures: shutter speedISO, and aperture. In digital photography, camera technology now features modes that can help adjust those settings for you. One of those modes is aperture priority. With it, the photographer selects a specific aperture value and the camera autoselects the proper shutter speed based on how much light it detects. 

Aperture priority and other shooting modes.

Here’s a quick breakdown of camera settings found on the mode dial of most digital cameras.

Aperture priority

In this camera mode, the photographer selects an aperture, and the camera chooses an appropriate shutter speed based on the available light.

Shutter priority mode

The opposite of aperture priority, the photographer sets the shutter priority mode at a certain speed and the camera autoselects a good aperture setting.

Program mode

Sometimes called auto mode, when the photographer selects program mode the camera autoselects both aperture and shutter speed.

Manual mode

The photographer is responsible for adjusting both the aperture and shutter speed in this mode.
