Wireless Multiple Flash Photography
Wireless Multiple Flash Basics
As shown below, a wireless multiple macro flash system basically
consists of a master unit (flash tubes/heads A and B) and slave unit(s)
C. Slave C can be used to eliminate shadows or create an accent light.
The flash exposure is controlled automatically to obtain a standard
exposure with both flash tubes/heads A and B, as well as with slave C
by itself.
