1. Match the aperture with the object and the goal of your pic. If you wanna shoot a landscape, use small aperture like f/16 or smaller (f/22, f/32).
2. Balance aperture and shutter speeed, to make perfect exposure.If the light is strong enough, usually the shutter speed is also high, so use small aperture.
3. To choose aperture you also should think about what ISO do you use.
