from the flash are used simultaneously.
Determine the bounce angle in reference to the distance to the
reflective surface, the distance from the camera to the subject, and
the focal length of the lens etc.

Rotating the flash by 90° to bounce light sideways is recommended.
If an angle of less than 90° is used, care should be taken to ensure
that direct light from the flash does not illuminate the subject.
