the existing light conditions. You can select the AE mode to have an aperture (iris) –
priority, shutter-priority, or set the options manually.

determined by how wide you open the lens diaphragm (iris adjustment), by how long
you keep the sensor exposed (shutter speed), and by other exposure parameters.
