Opening the aperture (reduce the aperture value)
Objects closer and farther than the
focused subject will be more out of
focus. For instance, if you take a picture
of a flower against a landscape with the
aperture open, the landscape in front
and behind the flower will be blurred,
emphasizing only the flower.
Closing the aperture (increase the aperture value)

The range in focus expands forward and
backward. For instance, if you take a
picture of a flower against a landscape
with the aperture narrowed, the
landscape in front and behind the flower
