Rear-Curtain Sync; To Create A Natural-Looking Stream Of Light; Slow Sync - Nikon F5 Instruction Manual

REAR-CURTAIN SYNC—

Normally in flash synchronization, the Speedlight fires at the
beginning of the exposure. When the shutter speed is slow, the
result is a streaking light pattern in front of the subject.
When Rear-Curtain Sync is set, the Speedlight fires at the end
of the exposure, turning available light into a stream of light that
follows the flash-illuminated moving subject.
Since Rear-Curtain Sync is especially effective at a slow shutter
speed, Slow Sync is automatically set at the same time that
Rear-Curtain Sync is set in Programmed Auto or Aperture-
Priority Auto exposure mode. To set a specific shutter speed,
set the F5 to Shutter-Priority Auto or Manual exposure mode.
• When using the SB-26, SB-25 or SB-24, note that the Rear-
Curtain Sync setting on the camera body is ignored. You must
set the Speedlight unit itself for Rear-Curtain Sync.
