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.

• Second-curtain synchronization is easier with bulb
• With the EOS 500N/Rebel G, 3000N/66/Rebel XSN, TTL autoflash is used with second-curtain synchronization
• Second-curtain synchronization does not work with the cameras picture taking mode
• To cancel second-curtain synchronization, press the <+> and <-> buttons simultaneously to turn off the icon on the LCD panel
