When insuffi cient light for correct exposure is indicated
When the SB-900 fires at full flash
output level, ready-lights on the
SB-900 and in the camera’s
viewfinder blink for approx. three
seconds after shooting.
In this case, underexposure may
occur. To compensate the exposure,
use a wider aperture or move closer
to the subject and reshoot.
The underexposure value (-0.3 to
-3.0 EV) is displayed on the SB-900’s
LCD panel for approx. three seconds
while the above ready-lights blink.
Pressing Function button 2 recalls
display of underexposure value in
TTL mode.
