If the image comes out dark or the contrast is low, the brightness and

3 Correcting the Brightness and Contrast Automatically
If [z2: Highlight tone priority] is set to [Enable], the Auto Lighting
Optimizer will be set automatically to [Disable] and the setting cannot be
changed.
Depending on the shooting conditions, noise may increase.
If a setting other than [Disable] is set and you use exposure
compensation or flash exposure compensation to darken the exposure,
the image may still come out bright. If you want a darker exposure, set
this function to [Disable].
If multiple exposure shooting (p.180) is set, the Auto Lighting Optimizer
will be set automatically to [Disable]. When the multiple exposure
shooting is canceled, the Auto Lighting Optimizer will revert to the
original setting.
In step 2, if you press the <B> button and uncheck <X> the [Disable
during man expo] setting, the Auto Lighting Optimizer can be set in the
<a> mode.
