4.7 Flash techniques
4.7.1 Bounce flash (Fig. 21)
Photos shot with full frontal flash are easily recog-
nized by their harsh, dense shadows. This is often
associated with a sharp drop in light from the
foreground to the background. This phenomenon
can be avoided with bounce flash because the dif-
fused light will produce a soft and uniform rendi-
tion of both the subject and the background. For
this situation the reflector is turned in such a man-
ner that the flash is bounced off a suitable reflec-
tive surface (e.g. ceiling or wall of the room).
The reflector can be turned vertically up to 90°.
The reflector head is mechanically interlocked in
its basic position. Press the pushbutton to unlock
and turn the reflector head.
When turning the reflector vertically, it is essential
to ensure that it is moved by a sufficiently wide
angle so that direct light can no longer fall on the
subject. Consequently, always turn the reflector at
least to the 60° lock-in position. The distance
readings on the LC display will disappear. The
flash-to-subject distance via the ceiling or wall is
an unknown magnitude.
The light bounced off the reflecting surfaces pro-
duces a soft and uniform illumination of the sub-
ject. The reflecting surface must be white or have
a neutral colour, and it must not be structured
(e.g. wooden beams in a ceiling) as these might
cause shadows. For colour effects just select the
reflective surface in the desired colour.
Take into account that the maximum flash
range is considerably diminished when
bouncing the flash. The following rule of
thumb will help you determine the maxi-
mum flash range for a room of normal
height:
