Shutter Speed and Aperture Value
The same exposure can be achieved with different
combinations of shutter speed and aperture value, allowing
you to freeze or blur motion and control depth of field. The
following figures show how shutter speed and aperture value
affect exposure. When the ISO sensitivity setting (A81) is
changed, the range of shutter speeds and aperture values at
which the correct exposure can be obtained also changes.
