Using Rear- or Second-Curtain Synchronization
When you photograph a moving subject with a ash and 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 in two different ways.
The rst, which is called front-curtain or rst-curtain ash sync, synchronizes the ash with the camera’s
shutter release so that the ash res at the beginning of the period when the shutter opens. This causes
motion blur and light trails to appear in front of moving subjects.
The second method, which is called rear-curtain or second-curtain sync, synchronizes the ash to re near
the end of the exposure. Since rear-curtain sync causes motion blur and light trails to appear behind moving
subjects, it creates a more realistic impression of movement and is most often preferable to front-curtain sync.
When rear-curtain sync is activated, the rear-curtain sync icon (
) appears on the LCD.
The VX-710N supports rear-curtain sync modes on cameras that offer the setting. Consult your camera’s
instruction manual to nd out how to activate it. 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.
Note: In i-TTL mode, the VX-710N will re a preash followed by the primary ash.
