Bounce Flash With A Reflector Card; Close-Ups / Macro Shots; Flash Synchronisation; Automatic Flash Sync Speed Control - Metz MECABLITZ 48 AF-1 digital Mode D'emploi

main reflector is moved to a position of greater/equal 70 mm in order to
prevent the subject from being additionally illuminated by dispersed light.
The range and position of the main reflector is 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 above out
of the reflector head and forwards.
• Hold the reflector card and push the wide-angle diffuser
reflector head.

10.3 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 unlocking button and tilt the reflector downward.
Certain minimum lighting distances must be maintained for close-up shots to
avoid over-exposure.
The minimum lighting distance is approximately 10% of the maximum
flash range indicated in the display. When the reflector head is tilted
downwards, the maximum flash range flashes as an indication. For close-
up shots, make sure that the flash light is not shaded by the lens!

11 Flash synchronisation

11.1 Automatic flash sync speed control

Depending on the camera model and camera mode, the shutter speed is swit-
ched to flash sync speed when flash readiness is reached (see the camera's ope-
can bring out high-
rating instructions).
Shutter speeds cannot be set faster than the flash sync speed, or they are swit-
ched automatically to the flash sync speed. Various cameras have a sync speed
range, for example from 1/30 sec to 1/125 sec (see the camera's operating
instructions). The sync speed set by the camera depends on the camera mode,
the ambient light, and the focal length of the lens used.
back into the
Shutter speeds slower than the flash sync speed can be set according to the
camera mode and the selected flash synchronisation (see 11.3 and 11.4).
If a camera with a between-the-lens shutter and high-speed synchronisa-
tion (see 7.3) is used, flash sync speed is not controlled automatically. As
a result, the flash can be used at all shutter speeds. If you need the full
light output of the flash unit, you should not select a shutter speed that is
any faster than 1/125 sec.

11.2 Normal synchronisation

In normal synchronisation the flash unit is triggered at the beginning of the shut-
ter time (first curtain synchronisation). Normal synchronisation is the standard
mode on all cameras. It is suitable for most flash shots. The camera, depending
on the mode being used, is switched to the flash sync speed. Speeds between
1/30 sec. and 1/125 sec. are customary (see the camera's operating instruc-
tions). No settings are necessary on the flash unit, nor is there any display for
this mode.

11.3 Second curtain synchronisation (REAR)

Some cameras offer the option of second-curtain synchronisation (REAR), in
which the flash unit is not triggered until the end of the exposure time. This is
