z About the wireless flash channels
As soon as the wireless flash is selected, the channel information of the external flash is transferred to the
camera. Change the channel of the external flash when another photographer is using a wireless flash
nearby and his/her built-in flash light triggers firing of your flash.
To change the channel of the external flash, refer to the operating instructions supplied with it.
When shooting with the flash, you can adjust the amount of flash light alone, without
changing the exposure compensation. You can change the exposure of a subject which is
within the flash range, while leaving the exposure of the background, which is out of the flash
range, as it is.
1 Display the Flash mode screen with the function dial and the Fn button (page 43).
2 Select the Flash compensation with V.
3 Select the desired value with b/B on the controller, then press the center of the controller.
