Selecting a Flash Sync Setting

You can use the following procedure to change the timing of
the flash. By using the flash sync setting, you can control
blur produced by movement.
Front-curtain and Rear-curtain Sync
Front-curtain sync causes the flash to fire immediately after
the shutter opens. Because of this, the blur created by move-
ment appears in front of the moving object (creating the im-
pression that the object is moving backwards).
Rear-curtain sync causes the flash to fire immediately before
the shutter closes. In this case, the blur created by move-
ment appears behind the moving object (creating the im-
pression that the object is moving forward).
