Flash Compensation

Controls used

Flash compensation (available only in P, S, A, and M modes) is used to alter flash output by from –3EV to +1EV in increments of 1/3EV, changing the brightness of the main subject rela- tive to the background. Flash output can be increased to make the main subject appear brighter, or reduced to prevent unwanted highlights or reflections.

Flash compensation is shown in the shooting information display. Normal flash output can be restored by setting flash compensa- tion to ±0.0. Flash exposure compensation is not reset when the camera is turned off.

Flash compensation is also available with SB-400, SB-800, SB-600, and SU-800 flash units ( 99).
