7. Second-Curtain Synchronization

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.
