See the difference control points make
Control points can make a huge difference to your editing, enabling you to make targeted adjustments with ease. To see how the various sliders have changed an area of an image, use the Color Control Point sub-menu to toggle between a before and after view. Within the sub-menu, next to each individual control point, there is a tick box. When the box is ticked your slider changes are visible for that particular control point, and when unticked you do not see any changes you have made using that control point.
