If [8C.Fn II -3: Highlight tone priority] is set to [1: Enable], the Auto
Lighting Optimizer will be set automatically to [Disable] and you cannot
change this setting.
Depending on the shooting conditions, noise might increase.
If a setting other than [Disable] is set and you use exposure
compensation, flash exposure compensation, or manual exposure to
darken the exposure, the image might still come out bright. If you want a
darker exposure, set this to [Disable] first.
In Basic Zone modes, [Standard] is set automatically.
