Adjustment Controls allow you to manually adjust the settings applied to images in the Review Window.
Changing any control or slider places the current Review Window in Custom Mode. The pop-down menu
will show
“Current Unsaved Setting”
indicating that a control has been manually adjusted.
Until you choose another mode or a saved setting, the current settings in the palette will be applied to each
image appearing in the associated Review Window. When multiple Review Windows are open, the palette
settings will reflect the current topmost active Review Window.
