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 /
8000
to 1 /
60
s with Auto FP High-
Speed Sync; 0 299).
Red-eye
reduction
If flash unit supports red-eye reduction, choose this
mode to reduce “red-eye” effect sometimes caused by
flash. Not recommended with moving subjects or in
other situations in which quick shutter response is
required. Do not move camera during shooting.
Red-eye
reduction with
slow sync
Combines red-eye reduction with slow sync. Use for
portraits taken against a backdrop of night scenery.
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.
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.
Flash off
Flash does not fire.
