Description
Use to include background lighting in
portraits. Red-eye reduction is combined
with slow shutter speeds to capture
background lighting at night or under
low light.
･ Note that photos may be prone to
blurring due to camera shake at slow
shutter speeds.
･ Use of a tripod is recommended.
The flash fires just before the shutter
closes, creating the effect of a stream of
light behind moving light sources.
･ Selecting P or A after choosing this
option sets the flash mode to slow
sync.
･ Note that photos may be prone to
blurring due to camera shake at slow
shutter speeds.
･ Use of a tripod is recommended.
The flash does not fire.
