Default Color-Space Profiles
See Appendix: Supplied Color Profiles
for more information on the default
RGB color-space profiles. The
"NKCMYK.icm" (Windows) and "Nikon
CMYK 4.0.0.3000" (Macintosh) CMYK
profiles provided with Capture NX are
general-purpose, almost neutral profiles
that are not based on a specific ink
set, making them suited for use where
output conditions are not known.

Levels & Curves
The Curves Tool and the LCH
Editor
The Curves tool controls the distribu-
tion of tones in the red, green, and
blue channels and in the RGB master
channel, and provides visual feedback
on the amount of tone information lost
through editing. The LCH Editor is a
better tool for making fine adjustments
to luminosity (brightness), color satura-
tion, and hue; note, however, that
changes to these settings may produce
results that exceed the dynamic range
of the RGB channels.
Auto Contrast Settings
Auto contrast, shadow, and highlight
settings can be adjusted in the Levels &
Grid tab of the Preferences dialog.
The Curve Edit Display
Although values for input and output
in the Curves palette range from zero
to 255 (eight-bit precision, familiar to
users of other image editing software),
the results of any changes to curves are
calculated at a precision of sixteen bits.
This allows twelve-bit RAW data to be
modified without lowering the quality
of the output.
214) for
The Histogram (RAW / 16-Bit
TIFF Images Only)
To reduce display times when dealing
with large amounts of image data,
Capture NX may display a histogram
containing vertical lines.
Sampling White Point or
Black Point for the Current
Channel
By default, sampling sets the white
point or black point for all channels
and displays the master channel. To set
the white or black point for the current
channel only, sample the image while
pressing Ctrl (Windows) or Command
(Macintosh). Midpoint cannot be
sampled for a single channel; regard-
less of the channel currently selected,
sampling the image for midpoint always
sets the mid point for all channels and
displays the master channel.
