Shooting/Exposure Modes – Priority Modes

Aperture Priority (sometimes shown as just “A”)
This is my fav because I’m usually not shooting moving subjects and want to control depth of field. In this mode you choose the aperture (again using one of the command dials) and the camera chooses the shutter speed that will produce a “good” exposure.

Shutter Speed Priority (sometimes shown as just “S”)
In this mode you choose the shutter speed (again using one of the command dials) and the camera chooses the aperture that will produce a “good” exposure.
