SECOND CURTAIN SYNCHRONIZATION
When you photograph a moving subject with slow synchronization, usually the furrow of the subject will be
exposed in front of the subject. The ordinary flash light will fire when the first shutter curtain is fully opened,
thus the subject will be exposed from the time flash is fired to the time the shutter is closed (This is called
First Curtain Synchronization). When you use second curtain synchronization, the flash will fire just before
the second curtain begins to closes, and the subject will be exposed by ambient light from the time the
shutter opens until the flash fires. The furrow of the subject will therefore be exposed behind the subject,
creating a more natural effect.
