Adjusting Selected Colors (Color Control Points)

Use the tool in the toolbar to selectively brighten, darken, or modify colors. Capture NX-D automatically chooses the area affected according to the placement of the control point.

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 (you can choose the adjustment sliders displayed using the Color Control Point tool in the retouch palette as described on “The Color Control Point Tool”).

Color Model

You can click the triangle at the bottom or top of the sliders to switch between the current color model (BCS, RGB, or HSB) and ALL.

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.

Adding Control Points

The practical maximum for the number of control points that can be added to a single image is about 100.

Zoom

You cannot zoom in by double-clicking the preview image while color control point mode is in effect. Use the navigation palette or the zoom commands in the View menu.

The Color Control Point Tool

Color control points can be fine-tuned using the color control point tool in the retouch palette.

Deselecting Control Points

To deselect the current color control point, click it while pressing the Ctrl (or on Mac computers, the /command key) or choose Deselect in the Edit (or on Mac computers, the Capture NX-D) menu.

Copying Color Control Points

Copy and paste can be used to create multiple control points with the same size and type of effect. To copy a color control point, select it in the preview display or retouch palette and use the Copy and Paste commands in the Edit (or on Mac computers, the Capture NX-D) menu.
