Compose a picture and shoot with flash.
Confirm that the red ready-lights on the SU-800
and SB-R200 are on, then release the shutter.
• For details on test firing, refer to page 88.
In the TTL mode, when the SB-R200 flash has fired at its
maximum output and underexposure may have occurred, the
red ready-light on the SB-R200 blinks for approx. 3 sec. (The
ready-lights on the SU-800 and in the camera's viewfinder do
not blink.)
To compensate, set a higher ISO sensitivity or use a wider
aperture and reshoot.
