amount. Compensation amount will not be displayed. Exposure amount can be
confirmed by pressing the flash exposure amount.
■ It is possible to use the camera for flash exposure compensation of the
external flashgun. If the setting is done by both camera and flashgun, then the
camera’s setting will have priority over the flash’s setting.
WARNING!!
• Once you set the flash Exposure Compensation, the camera will continuously
hold this mode, until the compensation amount is reset to 0.0 value.
Combination of Exposure Compensation and Flash Exposure Compensation
It is possible to make adjustments by using the exposure compensation together
with the flash exposure compensation, such as making the background brighter
and preventing unwanted flash reflections from the subject.
For instance, set the exposure compensation to +2 and the flash exposure
compensation to –2, and the background exposure will be 2 stops over exposed
and the flash exposure be 0 (appropriate).
■ If exposure compensation and flash exposure compensation are set, will
be displayed on the display on the LCD panel, only the exposure
compensation amount will be displayed.
