Flash Compensation

Flash compensation is used to alter flash output from the level suggested by the
camera, changing the brightness of the main subject relative to the background.
Flash output can be increased to make the main subject appear brighter, or reduced
to prevent unwanted highlights or reflections.

Press the

M (Y) button and rotate the sub-command dial until the desired value is

displayed in the control panel. Flash compensation can be set to values between
–3 EV (darker) and +1 EV (brighter) in increments of




EV. In general, choose

positive values to make the subject brighter, negative values to make it darker.

At values other than ±0, a

Y icon will be displayed in the control panel and

viewfinder after you release the

M (Y) button. The current value for flash

compensation will be displayed when the

M button is pressed.

Normal flash output can be restored by setting flash compensation to ±0.0. Flash
exposure compensation is not reset when the camera is turned off.


Optional Flash Units

Flash exposure compensation is also available with an optional SB-900, SB-800, SB-600, SB-400,
or SB-R200 flash units.
