Nikon SB 700, SB-700 user manual Rear-curtain sync, Red-eye reduction/red-eye reduction slow sync

Red-eye reduction/red-eye reduction slow sync

To prevent subject’s eyes from appearing red in color pictures shot in low light, the SB-700 fires three flashes at reduced output moments before the picture is taken.

•With red-eye reduction slow sync, red-eye reduction is combined with slow-sync flash.

•Since slow shutter speeds are normally used in red-eye reduction slow sync, use of a tripod is recommended to prevent camera shake.

Rear-curtain sync

In normal flash photography, when photographing fast-moving subjects at slow shutter speeds at night, pictures can appear unnatural because the subject frozen by the flash appears behind or within the blurred movement. Rear-curtain sync flash creates a picture in which the blur of a moving subject appears behind the subject and not in front.

•In front-curtain sync, the flash fires immediately after the front curtain is fully open; in rear-curtain sync, the flash fires moments before the rear curtain starts to close.

•Since slow shutter speeds are usually used, use a tripod to prevent camera shake.
