How to use colour control points for localized edits
Alignment and sizing
Hover over the transparent circle at the top of the overlay. The cursor will change to a compass-style pointer, indicating you can click-and-drag the control point to move it. To set the size of the area affected, hover over the circle at the other end of the line to access a slider; drag it left or right to increase or decrease the size.
Changing colours
Click the arrow icon below the overlay to open an extended menu. Use the Hue slider to alter the shade of colour, and add extra depth using Saturation. Warmth can warm up or cool down the area under the control point, think of this as a localized ‘white balance’ effect. The Red, Green and Blue colour channels can also be adjusted.
Brightness and contrast
Brightness will lighten or darken the area and can be used for dodging and burning. With an appropriately sized control point you can use it as a localized pseudo ‘fill flash’ effect, if you set the brightness scale to a positive number. Contrast can be used to add or remove emphasis from the area under the control point.
Resetting and removing
If your changes to the control points have not improved your shot, use the ‘Reset’ button to return all of the control point sliders back to their default values. To remove a control point, use the sub-menu and select the point you wish to remove. Move to the right of the tick box and a cross will appear; click on this to remove the control point.
