Using the Built-in Flash
y Flash Exposure CompensationN
In the same way as normal exposure compensation, you can set exposure compensation
for flash. You can set flash exposure compensation up to ±2 stops in 1/3-stop increments.
Increased exposure
Decreased exposure
If you set flash exposure compensation with both the EX-series Speedlite and
camera, the Speedlite's flash exposure compensation setting will override the
camera's. If you set EX-series Speedlite's flash exposure compensation with the
flash, any flash exposure compensation set with the camera will be overridden.
The exposure compensation amount will remain in effect even after the
<4> switch is set to <2>.
The procedure is the same when using an EX-series Speedlite. The
Speedlite's flash exposure compensation can be set with the camera.
