RADIUS
The Radius controls the size of the
edge to display in the resulting image.
Settings for this slider are dependant
on the size of the image, so a radius
setting that works well for one image
may not be sufficient for an image with
a higher resolution.
Click OK to apply the High Pass feature
to your image. The cancel button can
be selected to prevent the application
of the High Pass feature.
Unsharp Mask
The Unsharp Mask feature increases the
apparent sharpness of your image by
enhancing the edges of objects in your
image. Unsharp Mask works by increas-
ing the contrast of edges throughout
your image and features controls over
Intensity, Radius (halo width), and
Threshold. The Unsharp Mask Tool from
Capture NX is unique in that it always
applies its sharpening to the luminos-
ity of the image, which prevents any
unwanted color shifts from occurring
within your image.
Please note : It is recommended that
you zoom your image to 100% while
determining the amount of sharpening
to apply to your image.
CHANNEL
First select the channel that you wish
to sharpen. Additional channels may be
selected later, after you have modified
the settings for the first channel. By
default the RGB option will be selected,
which enables you to sharpen all three
channels (Red, Green, and Blue) of your
image simultaneously. You can choose
to sharpen RGB or any individual color
channel individually (Red, Green, Blue,
Cyan, Magenta, or Yellow).
INTENSITY
You can then select the intensity of
the sharpening effect that you want to
apply. The higher the sharpening inten-
sity, the more pronounced the sharpen-
ing effect will be on your image. If the
Intensity setting is set too high it can
create an oversharpened and artificial
looking image.
RADIUS
The Radius (halo width) slider enables
you to increase the reach of the sharp-
ening effect. The higher the radius
setting, the wider the edges in the
sharpened image will appear. A radius
setting that is too high will produce
visible halo artifacts, which can appear
as white outlines around the objects.
