Black Control Point The black control point enables you to place a control point directly on your image, and to cause that targeted color to not only become black, but also to neutralize the dark tones of your image. Black control points are normally set on what should be the darkest point of the image and are used to set one end of the dynamic range of the image. The Double Threshold option in the "Histogram" section of the Photo Info palette is designed specifically to help you locate the darkest and lightest sections of your image. Original Image Final Image To add a black control point to your image, follow these steps: 1 Click on the black control point icon in the toolbar. The cursor will change to a crosshair. 2 Identify the object you would like to be the darkest object in the image and click on that object to place a black control point. A B / W / N Control Point step will be added to the Edit List palette, with a black control point sub-step. You can reposition the black control point by clicking and dragging it. Please note that you may only add one black control point to each B / W / N Control Point step. Chapter 13 - The Toolbar | Black Control Point 95
