Metz Mecablitz 54 MZ-3 - Manual (Page 38)

6.1 Bounce flash with secondary reflector
The secondary reflector produces frontal fill-in light
when the flash is bounced.
Use of the secondary reflector is only meaning-
ful in bounce flash photography.
The secondary reflector is switched on and off with
switch
. A flashing symbol on the LC display of
the mecablitz merely indicates that the main reflector
has not yet been turned.
Activation of the secondary reflector assigns approx.
85% of the emitted light to the main reflector and 15%
to the secondary reflector. These %-values can differ
somewhat when shooting with partial light output and
secondary reflector.
The light output of the secondary reflector can be redu-
ced by approx. 50% with a light reducing filter if it is too
bright. For this purpose shift the light reducing filter side-
ways, remove from the mecablitz, turn by 180°, place
over the secondary reflector and push down until it
audibly clicks into position.
The sub-modes stroboscope, ETTL HSS, 3D
multi-sensor and TTL HSS are not possible in
conjunction with the secondary reflector.
6.2 Bounce flash in automatic and TTL flash
mode
Prior to picture taking it is advisable to check whether
sufficient light is available for the selected aperture. For
this purpose proceed in the manner described in Chapter
„10. Correct exposure indication“.
6.3 Bounce flash in manual flash mode
The required aperture on the camera in the manual flash
mode is best established with a flash meter. If a flash
meter is not available, observe the following rule of
thumb
Camera aperture =
guide number
Flash-to-subject distance x 2
to establish a guide value for the aperture that can then
be varied by ±1 f-stop for the shot to be taken.
