Normally, the
flash
fires in
synchronization
with
the
first
shutter
curtain
when
the shutter
is fully
open.
With
second-curtain
synchronization,
the
flash
fires
immediately before
the
second
shutter
curtain
closes
at
the end
of
the
exposure.
With
second-curtain
synchronization
and
a slow
shutter
speed,
you
can
create
a trailing
blur
(illuminated
by ambient
light)
that
trails a
moving
subject
(illuminated
by the
flash)
to
give
a
natural-looking
illusion
of
motion.
