Bounce flash photography
Enable to shoot in all flash modes.
If there is a wall or similar object behind the subject, fire the flashing
section pointed at a white ceiling or wall to light the subject using reflected
light. As the reflected light spreads in and around the subject over a wide
area to light the subject, you can create softer images with fewer shadows
on the subject and wall.

Decide on the angle of the flashing section so that the angle
of incidence and reflecting angle on the reflecting surface are
equal.
The shooting distance means the total distance obtained by adding the
distance from the flashing section to the reflecting surface to the
distance from the reflecting surface to the subject.
