Advisories & Additional Notices
Unsharp Mask
Unsharp Mask
Unsharp Mask sharpens edges without
affecting color balance by making
adjustments only to luminosity (bright-
ness). The effect is the same as
performing Unsharp Mask with the
Luminosity channel selected in the
Adobe Photoshop Lab color model. If
Unsharp Mask is applied to a single
channel, such as red, the values for
ab (chrominance) are used to deter-
mine what points in the image are red,
and Unsharp Masking applied to the
Luminosity channel for those points
only. An intensity of around 20% in
Capture NX is roughly equivalent to
100% in Adobe Photoshop. No sharp-
ening will be applied if Intensity is set
to zero. Intensity must be set to at least
1% if sharpening is to apply.
Color Aberration Control
Lateral Chromatic Aberration
The refractive index of the lens varies
slightly with the wavelength (color) of
light. This results in changes in image
magnification towards the edges of
the image, producing a phenom-
enon known as lateral (or transverse)
chromatic aberration.
Batch Processing
Before Using Batch
Processing
To ensure that desired results are
achieved, we recommend processing
a test image before beginning batch
processing. Batch processing will apply
the same adjustments to each image
selected, and cannot be used to adjust
settings separately for each image;
instead, the images must be opened
one at a time in order to make separate
adjustments manually for each image.
Error Messages
If an invalid file name or other error
is identified while creating a batch
process, a message will be displayed.
Review the message and adjust the
batch settings as directed in the
message.
