Helpful Hints:
With bounce flash photography, it is neces­
sary to adjust the flash head so that the sub­
ject is not directly illuminated by the flash. If
you only tilt the flash up a few degrees ex­
posure will not be uniform. The easiest way
to use bounce flash is to tilt the flash head
up 90° and bounce off a ceiling.
The bounce surface should be white or
nearly white, fairly large and highly reflec­
tive. A colored, reflecting surface may
cause the subject to appear tinted that col­
or. The subject color may also be
disappointing if the surface reflects poorly.
A very high ceiling does not make a good
surface for bounce flash; a solution would
be to bounce the flash off a white card
reflector. Generally, the closer the flash is to
the bounce surface, the brighter and higher
in contrast the picture will be.
