Slow-sync flash
!
!
!
!
!
The flash is controlled at a slow shutter speed to obtain the correct exposure for both the main subject and
background in low-light situations.
Since slow shutter speeds are normally used, use of a tripod is recommended to prevent camera shake.
For more details on the example photos, see the separate booklet, “A collection of example photos”.

2nd curtain sync
!

In normal flash photography, when shooting fast-moving subjects at slow shutter speeds, unnatural-looking
pictures can occur, because the subject frozen by the flash appears behind or within the blurred
movement . Rear-curtain flash sync creates a picture in which the blur of a moving subject (for example, the
taillights of a car) appears behind the subject and not in front.
In front-curtain sync, the fl ash fi res immediately after the front curtain opens completely; in rear-curtain
sync, the flash fires just before the rear curtain starts to close.
Since slow shutter speeds are usually used, use a tripod to prevent camera shake. This function does not
operate in Repeating fl ash operation.
In multiple fl ash, the master fl ash unit can be set to either front-curtain or rear-curtain sync fl ash. However,
the remote units cannot be set to rear-curtain sync flash.
