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
7.9).
Using the secondary reflector is generally practical and feasible only for
bounce flash with a swivelled or tilted main reflector
not swivelled or tilted, the secondary reflector will not be activated for the shot.
If the light from the secondary reflector is too bright, it can be reduced by half in
the Select Menu (see 7.9).
☞ 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 and tilt the reflector downward.

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

can 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
with a correction value. The extent of the correction depends on the contrast bet-
ween subject and background.
In TTL, E-TTL and automatic flash modes, manual flash exposure correction fac-
tors of from -3 EV (f-stops) to +3 EV (f-stops) can be adjusted on the flash unit in
1/3 step increments.
Many cameras have a setting element for exposure corrections that can also be
used in TTL flash mode. Please refer to the information in the camera's operating
instructions.
Dark subject in front of a bright background:
Positive correction value (approximately +1 to +2 f-stops EV).
Bright subject in front of a dark background:
Negative correction value (approximately -1 to -2 f-stops EV).
When a correction value is set, the flash range indicated on the flash unit display
may change as it adjusts to the correction value (depending on the type of
camera). For adjustments, see 6.4.
☞ Manual flash exposure correction is possible in TTL flash mode only if the
camera supports this function (consult the camera's operating instruc-
tions). If the camera does not support this function, the adjusted correction
value will have no effect. For some camera models, the manual flash
exposure corrections must be adjusted on the camera. If this is the case,
no correction value will appear on the flash unit display.
