Color Control Points

When you place a color control point, Capture NX‑D automatically detects the color at the chosen point and selects all similar colors in the surrounding area. The effect is controlled by sliders: a size slider controlling extent of the area selected and (at default settings) three adjustment sliders for adjusting Brightness, Contrast, and Saturation in the selected area. Sliders can be adjusted by dragging the handles (●) left or right or by placing the mouse cursor over a handle and rotating the scroll wheel. You can choose the adjustment sliders displayed from the color model menu for the retouch palette Color Control Point tool.

Using Color Control Points

Follow the steps below to add and adjust color control points.

1. Click the button to enter color control point mode (to exit color control point mode, click the button again).

   

2. Click the image to add a color control point and drag it to the area you want to modify.

   

3. Adjust the size of the control point by dragging the handle of the size slider left or right: the longer the slider, the greater the area affected. The effect applies to the area shown by a dotted line and diminishes with the distance from the control point.

   

4. Drag the handles of the adjustment sliders left or right to adjust the selected color. The illustration shows the brightness slider being used to adjust the brightness of the sky: the effect applies only to the blue of the sky, leaving the color of the building unaffected, and diminishes with the distance from the control point.

   

   The size and adjustment sliders can be fine-tuned using the color control point tool in the retouch palette.

5. Repeat Steps 2 through 4 to add color control points as needed.
