Group Control
Firing group A
If you need more flash output or wish to perform more sophisticated lighting, you can
increase the number of receiver units. Simply set an additional receiver unit to the firing
group (A, B, or C) whose flash output you want to increase.
For example, if you set a firing group with three receiver units to <
>, the three units are
treated and controlled as a single firing group A with a large flash output.
Caution
To fire the 3 firing groups A, B and C together, select <
>. With the
<
> setting, firing group C does not fire.
If you shoot with firing group C pointing directly toward the main subject,
overexposure may result.
Note
The flash ratio of 8:1 to 1:1 to 1:8 is equivalent to 3:1 to 1:1 to 1:3 (1/2-stop
increments) when converted to the number of stops.
