4.7.2 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 fold down the reflector.
For close-ups it is necessary to ensure that certain
minimum lighting distances are maintained to
avoid overexposure.
The minimum lighting distance is approx.
10 per cent of the maximum flash range
indicated on the LC display. Since the maxi-
mum flash range is not indicated on the LC
display when the reflector is swivelled
down, then be guided by the maximum
flash range indicated by the mecablitz
when the reflector is in its normal position!
4.8 Flash synchronisation
4.8.1 Normal synchronisation (Fig. 22)
In normal synchronisation the mecablitz is trigger-
ed at the beginning of the exposure time (1st cur-
tain synchronisation). Normal synchronisation is
the standard mode on all cameras, and is suitable
for most flash shots. Depending upon the given
mode, the camera is changed over to flash sync
speed, the customary one being between 1/30th
sec. and 1/125th sec. (see the camera's opera-
ting instructions). No settings have to be made on
the mecablitz, nor is there any display for this
mode.
4.8.2 REAR - Second-curtain synchroni-
sation (Fig. 23)
Some cameras offer the facility of second-curtain
synchronisation (REAR mode) triggering the
mecablitz by the end of the exposure time.
Second-curtain synchronisation is particularly
advantageous when using slow shutter speeds
(slower than 1/30 sec.) or when shooting moving
objects that have their own source of light.
Second-curtain synchronisation gives a more rea-
listic impression of movement because the light
streaks behind the light source instead of building
up in front of it, as is the case when the flash is
synchronised with the 1st shutter curtain! Depend-
ing on its operating mode, the camera uses shut-
ter speeds slower than its sync speed.
