Multi Lighting Applications
3. Wireless light-sensing application (S1 / S2)
Use the built-in flash or the set-top external flash as the master flash . Place the
flash in a variety of directions .
In indoor use the wireless optical signal can be reflected back through the wall .
So maybe more space i needed .
Due to a higher sensor sensitivity the wireless trigger sensing does have a
distance of up to 15 meters when using the S1 or S2 mode outside .
If a slave Flash Unit is used, test the S1 or S2 mode whether it is synchronous
before shooting . Don’t put any barriers between the master and slave Flash Unit .
The barrier will prevent to send a wireless light signal .
Make sure that the optic control sensor is towarded to the master Flash Unit .
The Flash Unit should not be used under sunshine .
