Flash Compensation
Flash compensation is used to alter flash output by from –3 EV to
+1 EV in increments of
1 /
3
EV, 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. In general, choose positive
values to make the main subject brighter, negative values to make
it darker.
To choose a value for flash
compensation, press the
M button
and rotate the sub-command dial
until the desired value is displayed
in the top control panel.
