16.2 Second curtain synchronisation (REAR, 2nd curtain, SLOW2)

Some cameras offer the option of second-curtain synchronisation (2nd curtain
mode), in which the flash unit is not triggered until the end of the exposure
time. This is particularly advantageous when used with slow shutter speeds (slo-
wer than 1/30 sec.) and moving subjects that have their own source of light.
With second-curtain synchronisation, a moving light
source will trail a light streak instead of building one
up ahead of itself, as it does when the flash is syn-
chronised with the first shutter curtain. Second-curtain
synchronisation thus produces a more „natural" image
of the photographic situation when there are moving
light sources. Depending on its operating mode, the
camera sets shutter speeds slower than its sync speed.
On some cameras, the REAR function is not possible in certain operating modes
(e.g., certain vari- or subject programmes). In that case, the REAR mode cannot
be selected, or the REAR function is automatically cancelled or ignored (see the
camera's operating instructions).

16.3 Slow synchronisation / SLOW

Various cameras feature slow flash synchronisation in certain modes. This set-
ting will give added prominence to the background at lower ambient light
levels. This is achieved by matching the shutter speed to the ambient light.
Accordingly, shutter speeds that are slower than the flash sync speed are auto-
matically adjusted by the camera. Some cameras automatically activate SLOW
synchronisation in connection with certain camera programs (e.g. „Av" apertu-
re priority, night shots program, etc.). No settings are made on the flash unit nor
is there any display for this mode.
☞ Use a tripod to avoid camera shake with slow shutter speeds!
