7. Second-Curtain Synchronization
Normally, the flash fires in synchronization with the first shutter curtain when
the shutler is fully open. With second-curtain synchronization, the flash fires
immediately before the second shutler 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.
