Rear-curtain sync
In normal flash photography, when shooting fast-moving subjects at slow shutter
speeds, unnatural-looking pictures can occur, because the subject frozen by the
flash appears behind or within the blurred movement (see photo below right).
Rear-curtain flash sync creates a picture in which the blur of a moving subject
(for example, the taillights of a car) appears behind the subject and not in front.
• In front-curtain sync, the flash fires immediately after the front curtain opens completely;
in rear-curtain sync, the flash fires just before the rear curtain starts to close.
• Available with cameras providing rear-curtain sync. You cannot set this mode on the
SB-800 directly, but must set it on the camera. For details, see your camera’s instruction
manual.
• Since slow shutter speeds are usually used, use a tripod to prevent camera shake.
• This function does not operate in Repeating flash operation.
• In multiple flash, the master flash unit can be set to either front-curtain or rear-curtain
sync flash. However, the remote units cannot be set to rear-curtain sync flash (p. 72).
