Second-Curtain Synchronization

When you photograph a moving subject with a ash and have a slow shutter speed (1/30 second or longer),

the ash 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 ash technique, also known as “dragging the shutter,” can be applied. Rear-curtain or

second-curtain sync synchronizes the ash to re 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 ash in this mode.

Note: In E-TTL mode, the VC-310C will re a pre-ash followed by the primary ash.
