Neutral Control Point
Neutral control points enable you to correct a color cast in your photograph by forcing the targeted color to
become neutral. In its default operation, the neutral control point will change the color values in the
targeted color so that the red, green, and blue values for that color are equal. Equalizing the red, green, and
blue values for a specific color causes that color becomes neutral, or without a specific color or hue. Neutral
control points are often most helpful if the image contains a neutral point of reference, for example, a gray
card. By selecting an object that is established as neutral, Capture NX 2 is able to calculate the difference
between that object and the color that is currently representing that object. The neutral control point will
remove the difference in color from the targeted object, as well as from the entire image. This results in a
color shift that affects the entire image.
One of the unique features of the neutral control points found in Capture NX 2 is that multiple neutral
control points can be added to the same image. This feature enables you to identify different objects and
neutralize more than one color cast that may appear in the image. When you use multiple neutral control
points, each control point will communicate with the other neutral control points in the same B / W / N
Control Point step of the Edit List palette to affect the entire image, correcting different objects and in the
process removing multiple color casts.
