Modeling Flash - Canon Speedlite 430EX II Mode D'emploi

Setting the Slave ID
Set the slave ID if you use two (A and B) or three (A, B, and C) slave
groups.

Modeling Flash

If the camera has a depth-of-field preview button, pressing it will fire the
flash continuously for 1 sec. This is called the modeling flash.
It enables you to see the shadow effects on the subject and the lighting
balance. You can fire the modeling flash for both wireless and normal
flash shooting.
Do not fire the modeling flash more than 10 consecutive times. If you
fire the modeling flash 10 consecutive times, allow the Speedlite to
rest for at least 10 min. to avoid overheating and deteriorating the flash
head.
The modeling flash cannot be fired with the EOS REBEL 2000/300 and
Type-B cameras (p.2).
