The Range control is a fast method of selecting multiple control points corresponding to a specific range of colors.
— Range: A gradient shows the range of hues currently being presented in the warping grid. Dragging the left and right handles of the Range control selection box lets you automatically select all control points corresponding to the hues that appear within the selection box. This is a fast way of selecting all points within a range of colors for uniform manipulation.
Auto Lock Controls
The Auto Lock controls enables DaVinci Resolve to automatically lock a border of control points surrounding any control point you select and adjust, which makes highly-specific color adjustments easier to accomplish.
— Auto Lock: Enables and disables this behavior.
— X Points Border: Lets you set how many points away from the control point you’re adjusting the border of locked control points that restricts your adjustments is. How large an area this ends up being depends on how many points you choose, and on the resolution of the warping grid. At higher grid resolutions, the same points distance isolates a smaller region of color.
Smoothing Controls
The smoothing controls let you “ease off” an adjustment you’ve made by progressively moving one or more selected control points towards their original default position in the warping grid.
— Smooth Chroma: Each click of this button rotates the angle of selected control points around the circumference of the circular warping grid towards their original position, bringing the hue of the adjusted colors closer and closer to the original hues of the image. Saturation is unaffected.
— Reset Chroma: Resets the angle of all selected control points to the original hues of those control points. Saturation adjustments are unaffected.
— Smooth Saturation: Each click of this button moves the position of a control point closer to its original position relative the center of the circular warping grid, thus bringing the saturation at that point closer to the original image saturation of the node’s input. Hue is unaffected.
— Reset Saturation: Resets the distance from the center of all selected control points to the original image saturation at those control points.
— Reset Luma: Resets luma to the original image values.
