4.3 Flash techniques
4.3.1 Bounce flash
Photos shot with full frontal flash are easily re-
cognized by their harsh, dense shadows. This is
often associated with a sharp drop in light from
the foreground to the background. This phenome-
non can be avoided with bounce flash because
the diffused light will produce a soft and uniform
rendition of both the subject and the background.
For this situation the reflector is turned in such a
manner that the flash is bounced off a suitable
reflective surface (e.g. ceiling or wall of the room).
The reflector can be turned verticall 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:

4.3.2 Close-ups/Macrophotography
The flash reflector can be swivelled down by an
angle of -7° to compensate for parallax error. For
this purpose depress the unlocking button of the
reflector and swivel down the reflector.
For close-ups it is necessary to ensure that certain
minimum lighting distances are maintained to
