Flash Exposure Compensation - Canon SPEEDLITE 580EXII Mode D'emploi

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. (If the
camera's exposure compensation is in 1/2-stop increments, flash
exposure compensation will be in 1/2-stop increments.)
If flash exposure compensation has been set with both the Speedlite and
camera, the Speedlite's flash exposure compensation amount will override
the camera's.
Setting the flash exposure compensation can be limited to only the <9>
dial. (C.Fn-13 → p.27)
