f Flash Exposure Compensation
In the same way as normal exposure compensation, you can set
exposure compensation for flash. The flash exposure compensation
amount can be set up to ±3 stops in 1/3-stop increments.
Generally, set an increased exposure compensation for bright subjects
and set a decreased exposure compensation for dark subjects.
If the camera's exposure compensation is set to 1/2-stop increments, flash
exposure compensation will be up to ±3 stops in 1/2-stop increments.
When the flash exposure compensation is set on both the transmitter and
the camera, the transmitter setting is given priority.
The flash exposure compensation amount can be set directly with <9>
without pressing the button (C.Fn-13/p.57).
