If you need more flash output or wish to
perform more sophisticated lighting, you
can increase the number of slave units.
Simply set an additional slave unit to the
firing group (A, B, or C) whose flash
output you want to increase. There is no
restriction on the number of units.
For example, if you set a firing group with three slave units to <
f
>,
the three units are treated and controlled as a single firing group A with
a large flash output.

Firing group A
To fire the three firing groups A, B, and C at the same time, set <

<

If you shoot with firing group C pointing directly toward the main subject,
overexposure may result.
With certain EOS film cameras that support E-TTL autoflash, you cannot
perform multiple flash wireless shooting with a flash ratio setting.
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.
