Bounce Flash Operation
Selecting flash head tilting/rotating angles
and a reflecting surface
Good results are most easily achieved when the flash head is tilted
up to use the ceiling as a reflecting surface.
Rotate the flash head horizontally to get the same effect when the
camera is held in the vertical position.
Illumination can be softened further when the light is bounced off
a ceiling or wall behind the camera, as opposed to in front of the
camera.
Select white and highly reflective surfaces to bounce the light off.
Otherwise, image colors will be influenced by the color of the
reflecting surface.
Avoid illuminating the subject directly to achieve successful bounce
flash photography.
The recommended distance between the flash head and the
reflecting surface is approximately 1 m to 2 m (3.3 ft to 6.5 ft), but
this number may vary depending on photographic conditions.
If the reflecting surface is not close enough, a piece of A4-size white
paper can be used instead. Check that the subject is exposed to the
bounced light before taking a picture.
