●●● 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 user’s 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. 58).
