Group Control
Firing group A
You can add more receivers when more light or sophisticated lighting is needed. For added
receivers, simply specify the flash group (A, B, or C) that you want to be brighter. Up to 15
receivers are supported.
For example, when three receivers are set to flash group < >, they are all controlled as
a single, high-output flash unit in group A.
Caution
To fire the three groups of A, B, and C, set to [A:B C]. Group C does not fire when
set to [A:B].
Aiming the units in flash group C directly at subjects may cause overexposure.
Note
Flash ratios from 8:1 to 1:1 to 1:8 correspond to 3:1 to 1:1 to 1:3 (in 1/2-stop
increments) as converted to number of stops.
