Flash Modes
The camera supports the following flash modes:
Flash mode Description
Front-curtain
sync
This mode is recommended for most situations. In
programmed auto and aperture-priority auto modes,
shutter speed will automatically be set to values
between
1
/250 and
1
/60 s (
1
/8,000 to
1
/60 s with Auto FP
High-Speed Sync).
Slow sync
Flash is combined with shutter speeds as slow as 30 s to
capture both subject and background at night or under
dim light. This mode is only available in exposure modes
e and g. Tripod is recommended to prevent blurring
caused by camera shake.
Rear-curtain
sync
In exposure modes f and h, flash fires just before the
shutter closes. Use to create effect of a stream of light
behind moving objects. In exposure modes e and g,
slow rear-curtain sync is used to capture both subject
and background. Tripod is recommended to prevent
blurring caused by camera shake.
Red-eye
reduction
In this mode (available only with SB-800, SB-600, and SB-400),
red-eye reduction pre-flash lights for approximately one
second before main flash. Pupils in subject’s eyes to contract,
reducing “red-eye” effect sometimes caused by flash. Owing
to one-second shutter-release delay, this mode is not
recommended with moving subjects or in other situations in
which quick shutter response is required. Avoid moving
camera while red-eye reduction pre-flash is lit.
