When used with the
F4
or F-801/N8008, the S8-24 lets you
synchronize the flash to the instant before the rear (second)
curtain begins to close.
Set the S8-24's flash sync mode selector to "REAR." This turns
available light into a stream of light that follows the flash-illumi-
nated moving subject.
Rear-curtain sync flash photography is most effective with
slower shutter speeds. Although the slowest possible shutter
speed for front-curtain sync flash photography
in
TTL mode
(with camera at
PO,
P,
PH
or A) is only 1/60 second, with rear-
curtain sync flash photography, depending
on
the background,
you can sl
ow
the shutter down to 30 seconds.
