U Point T
echnology
U Point technology powers Capture
NX’s series of Control Points: The Color
Control Point, the Black/White/Neutral
Control Points, and the Red-Eye Control
Point. These Control Points enable you
to create color and tonal enhancements
directly on the image, without first
making selections. You can also see the
effects of a Control Point immediately.
The Control Points powered by U Point
technology enable you to work with your
images without the need to perform a
complicated series of operations in a
particular order. Each Control Point works
together with other Control Points of the
same type. With every Control Point that
you apply to the image comes greater
control over specific objects in the image.
The more Color Control Points you apply,
for example, the greater control you have
over color in the image. The additional
Control Points ensure that the adjust-
ments you make are being applied to the
current object only, and placing a Control
Point on an object with default settings
prevents other Control Points from affect-
ing that object.
While the Black, White, and Neutral
Control Points were designed to control
the entire image globally, both the
Red-Eye and Color Control Points were
designed to control elements locally.
The Color Control Points work by
identifying an object based on a
number of criteria. When you place
your first Color Control Point, the
U Point technology identifies the
unique elements of the object on which
you place a Control Point, includ-
ing its position, color, saturation, and
texture. By identifying these elements,
the Color Control Point can deter-
mine the boundaries of the object in
order to affect only that object and
objects with like elements. Through
a unique mixing function, the effects
of the Color Control Point are applied
throughout the image so as to create a
natural-looking, seamless result. On the
next page you will find a series of steps
showing the original image, the effect
of the Control Point, and the selection
of the Control Point.

Technology
A key feature in Capture NX is U Point technology. The controls powered by U
Point technology enable you to modify sections of a photo directly, without having
to go through the time-consuming process of making a mask required in other
software applications.
