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; 
0 311).
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 programmed 
auto and aperture-priority auto exposure modes. Use of 
tripod is recommended to prevent blurring caused by 
camera shake.
Rear-curtain 
sync
In shutter-priority auto or manual exposure mode, flash 
fires just before the shutter closes. Use to create effect of 
a stream of light behind moving objects. In 
programmed auto and aperture-priority auto, slow rear-
curtain sync is used to capture both subject and 
background. Use of tripod is recommended to prevent 
blurring caused by camera shake.
Red-eye 
reduction
In this mode (available only with SB-900, 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 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.
Red-eye 
reduction with 
slow sync
Combines red-eye reduction with slow sync. Use for 
portraits taken against a backdrop of night scenery. 
Available only with SB-900, SB-800, SB-600, and SB-400 in 
programmed auto and aperture-priority auto exposure 
modes. Use of a tripod is recommended to prevent 
blurring caused by camera shake.
