Add Grain/Noise; Contrast: Color Range - Nikon 25338 User Manual

Add Grain/Noise...

The Add Grain / Noise feature enables
you to add the stylistic effect of either
grain or noise to your image. The grain
feature emulates different sizes of film
grain within your image, while the
noise feature applies random detail
to your image to approximate digital
camera noise.
Within the Add Grain/Noise dialog
you are provided with the following
controls:
GRAIN STRENGTH
Move this slider to the right to increase
the amount of grain or noise that is
applied to your image.
GRAIN COLOR
Use this feature to control whether or
not the grain or noise is made up of
color or black and white details.
GRAIN TYPE
Use this feature to choose the method
of grain or noise to apply to your
image. Choose from Small Grain,
Medium Grain, Large Grain, and Noise.
Click OK to accept the Add Grain/Noise
effect, or click Cancel to prevent the
effect from being applied to your
image.

Contrast: Color Range...

The Contrast: Color Range feature
enables you to control the contrast
between selected colors within an
image without introducing a color cast
to the entire image. Using this tool
isolates and identifies specific colors
and color relationships in much the
same way that black and white tones
are controlled using colored filters.
Within the Contrast: Color Range
dialog you are provided with the
following controls:
HUE
The Hue Slider selects the targeted
color range to apply contrast to. The
color that is selected will be lightened
in the image, while the complementary
color will be darkened. For example,
select the red portion of the spectrum
to emulate a red filter, which will
lighten reds and darken cyan, red's
complementary color.
