Each step may contain up to one Black and one White Control Point, while allowing for an unlimited number of Neutral Control Points. 165 White Control Point... The White Control Point enables you to place a Control Point directly on your image and to cause the targeted object not only to become white, but also to neutralize the light tones of your image. The White Control Point is not accessible while working within the Browser. White points are normally set on what should be the lightest point of the image and are used to set one end of the dynamic range of the image. The Double-Threshold function within the Photo Info's Histogram section is designed specifically to help you locate the darkest and lightest sections of your image. Please see page 100 for more information on how to use the Double-Threshold function. A White Control Point is often used in conjunction with a Black Control Point. Chapter 23 Control Points Menu After you place a White Control Point on your image a White Point dialog box appears next to the Edit List. The White Control Point can be repositioned by clicking and dragging on it. It can be deleted by selecting the control point and pressing the Delete key on your keyboard, and it can be modified by using the Control Point's slider.
