Rear-curtain sync
Unnatural-looking pictures can occur when using flash to shoot fast-moving
subjects at slow shutter speeds, because the subject frozen by the flash
appears behind or within the blurred movement (see photo below, right).
By using rear-curtain sync, however, the blur created by a moving subject,
such as the taillights of a car, will appear 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 that have rear-curtain sync. This mode cannot be set on the
SB-600; it can only be set on the camera. For more information, refer to your camera
instruction manual.
• As slow shutter speeds are normally used for rear-curtain sync, a tripod is
recommended to prevent camera shake.
• 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. 56).
