You can make exposure compensation for the flash illuminated subject only
without affecting the background exposure by modifying the SB-900’s flash
output level.
As a basic guide, some plus compensation may be necessary to make the
main subject brighter, and some minus compensation to make it darker.
Flash output level compensation is possible in i-TTL auto flash, Auto Aperture
flash, Non-TTL auto flash and Distance-priority manual flash modes.
t For cameras with a built-in fl ash featuring the exposure
compensation function
You can also set the flash output level on the camera. For details, see your
camera user’s manual.
If you compensate the flash output level on both the camera and the SB-900,
the exposure is modified by the sum total of both compensation values.
In this case, the SB-900's LCD panel shows only the compensation value set on the
SB-900.
