Enhancing Images
The settings that can be adjusted depend on the image quality setting in effect when the
photograph was recorded. Photographs taken at an image-quality setting of RAW can be
processed to adjust white balance, reduce the effects of dust, perform vignette control, or to
alter exposure com pen sa tion, im age sharp en ing, tone compensation, color mode, and hue
ad just ment from the set tings in effect at the time the photograph was taken. All images can
be processed using the tools in the Curves, Color Balance, LCH Editor, Color Booster, Photo
Effects, Unsharp Mask, Noise Reduction, D-Lighting, Red Eye Correction, and Size/Resolution
palettes. Images taken with an AF DX 10.5 mm f2.8G fi sheye Nikkor lens can also be pro-
cessed to reduce distortion.

Adjust tone, color balance, and contrast. There are two distinct
tools for this task: the Curves palette, which provides precise con trol
over tone, and the Color Balance pal ette, which features simpler
con trols.

Color Balance 66
Adjust luminosity (master lightness), color brightness, chroma (color
saturation, or vividness), and hue.

Convert images to black and white, sepia, or to other tints or ad-

channels.
Photo Effects 64
If the image lacks defi nition, you can sharpen out lines using the con-
trols in the Unsharp Mask pal ette. Unsharp mask only be ap plied at
the last step, after all other adjustments have been made.
Unsharp Mask 68
Reduce the noise common to pictures tak en with digital cameras.
Nikon Capture sup ports color noise reduction, edge noise reduction,
and moiré reduction (RAW images only).

The Curves Tool and the LCH Editor
The Curves tool controls the distribution 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 fi ne adjustments to luminosity (brightness), color saturation,
and hue; note, however, that changes to these settings may produce results that exceed the dynamic
range of the RGB channels.
