Second-Curtain Synchronization
When you photograph a moving subject with a flash and have a slow shutter speed (1/30 second or longer),
the flash will freeze the moving subject, and the long exposure will cause motion blur and light trails to appear
in the image, especially in low light.
This slow-sync flash technique, also known as “dragging the shutter,” can be applied. Rear-curtain or
second-curtain sync synchronizes the flash to fire near the end of the exposure. Since second-curtain sync
causes motion blur and light trails to appear behind moving subjects, it creates a more realistic impression of
movement. Use your camera’s shutter-priority or manual mode to control the amount of blurring and light trails
you capture by varying the shutter speed.
The VC-310C supports second-curtain sync modes on camera's that offer this setting. Check with your
camera's manual for instructions on how to operate the flash in this mode.
Note:
In E-TTL mode, the VC-310C will fire a pre-flash followed by the primary flash.
