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 fi res three fl ashes 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 fl ash photography, when photographing fast-moving subjects
at slow shutter speeds at night, pictures can appear unnatural because
the subject frozen by the fl ash appears behind or within the blurred
movement. Rear-curtain sync fl ash 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.
