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

