High Speed Sync / Rear-Curtain Sync
Off-camera High Speed Sync (not mounted on camera):
Within the wireless slave mode the flash can receive a high speed sync signal form
the master flash .
Note:
To use the high speed sync/Rear curtain sync correctly the camera flash mode
and shutter sped needs to be set properly .
High speed sync off the camera can be achieved in two ways:
1 . Wireless TTL trigger (The trigger needs to support high speed sync)
2 . Set the flash unit to slave c or slave n mode
a . To achieve the high speed sync in slave c mode, the Canon wireless instruc-
tions must be received . The built-in flash of the camera must be the master
flash . The maximum sync speed is only 1/200 or 1/250 . If you use a Canon
camera, the camera itself does not have high speed sync . Therefore you
should take an extra flash unit which has a master function and is connected
by the hot shoe mount to the camera . The master light will give the signal to
the slave light to make it high speed sync .
b . To achieve the high speed sync in slave n mode, you can use the built-in
flash of the Nikon camera as the built-in flash has the master function . Open
the Auto AP function in your camera and use the built-in flash . The built-in
flash will send the data only by the lamp, it does not sync in flash .
The camera menu access (only the latest Canon cameras)
The latest Canon cameras support that the flash can be operated through the
camera menu . Within the flash control menu of ”External flash function settings“
and ”External flash custom function settings“ flash releated parameters such as
switch E-TTL mode, manual flash mode and multiple flash mode (Multi), wireless
flash setting, surrounded by exposure, exposure compensation, the focal length and
the function of advanced options can be set .
