T
oolbar F4 – Black, White, and Neutral Contr
ol Points
White Control Point
The White Control Point enables you
to place a Control Point directly onto
your image, causing the targeted color
to become white, which is the first step
in removing a color cast from the light
tones in 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 establish 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 the 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 conjunc-
tion with a Black Control Point.
For additional information regarding
White Control Points, please see page
165.
Neutral Control Point
Neutral Control Points enable you to
correct a color cast in your photograph
by forcing the targeted color to become
a defined color or to become neutral.
The Neutral Control Point is not acces-
sible while working within the Browser.
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. By equalizing the red,
green, and blue values for a specific
color, that color becomes neutral, or
lacks saturation. Desaturating can be
helpful if the image contains a neutral
point of reference, a gray card, for
example. By selecting an object that
is established as neutral, Capture NX
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
change that affects the entire image.
