10 Flash techniques

10.1 Bounce flash
Bounce flash illuminates the subject more softly and reduces dense shadows. It
also reduces the drop in light from foreground to background that occurs for
physical reasons.
The main reflector of the flash unit can be swivelled horizontally and tilted
vertically for bounce flash. To do this, depress the reflector unlocking button
and tilt the reflector . To avoid colour cast in your shots, the reflective surface
should be colour-neutral or white. For frontal fill-in lighting, the secondary reflec-
tor can also be activated in the Select Menu (see 7.8).
When tilting the main reflector vertically, make sure that it is turned through
an angle that is wide enough to prevent direct light from falling on the sub-
ject. The reflector should be tilted at least as far as the 60° lock-in position.
For indirect flash operation in Auto Zoom Mode (AZoom; 6.2), the main reflector
is guided to the optimal position. The range and reflector position are not
displayed.

10.2 Bounce flash with a reflector card

The use of bounce flash with the integrated reflector card
lights in the eyes of human subjects.
• Tilt the reflector head upwards by 90°.
• Pull the reflector card together with the wide-angle diffuser
from the reflector head
• Hold the reflector card and insert the wide-angle diffuser
tor head.

10.3 Bounce flash with secondary reflector

When the main reflector is swivelled or tilted, the secondary reflector
also be activated in the Select Menu for frontal fill-in lighting of the subject
(see 7.7).

not swivelled or tilted, the secondary reflector will not be activated for the shot.
If too much light is emitted by the second reflector, it can be reduced by 1/2 or
1/4 in the Select menu (see 7.7).
The secondary reflector is not supported by the stroboscopic, modelling
light (ML) and remote flash modes. The secondary reflector does not flash
when the main reflector is in its normal position or is tilted downwards.

10.4 Close-ups / macro shots

In close-ups and macro shots, parallax error between the flash unit and lens may
result in shadows on the lower edge of the image. To compensate for this, the
main reflector can be tilted downwards by an angle of -7°. To do this, depress
the reflector release button
If the main reflector is tilted downwards, "TILT" is shown on the display to
indicate this. The second reflector is not supported and does not flash.
Certain minimum lighting distances must be maintained for close-up shots to
avoid overexposure.
The minimum lighting distance is approximately 10% of the maximum
flash range indicated on the LC display. For close-up shots, make sure
that the flash light is not shaded by the lens.

10.5 Manual flash exposure corrections

The auto flash exposure mode of the flash unit, as of most cameras, is adjusted
to a reflection factor of 25% (the average reflection factor of flash subjects). A
dark background that absorbs much of the light or a highly reflective bright
background (backlit shots, for example) may result in, respectively, underexposu-
re or overexposure of the subject.
To offset these effects, the flash exposure can be adjusted manually for the shot
