Canon ST-E2 - Flash Ratio with E-TTL II

10
With two slave units, you can vary the flash ratio and shoot with E-TTL
II autoflash.
To put the two slave units into two slave groups, set a different slave ID
for both slave units. To set the slave unit’s slave ID, see the Speedlite’s
instruction manual. Set the left slave unit’s ID to A, and the right slave
unit’s ID to B.
