Adjust Menu
to produce quick contrast or brightness
effects that you can paint in selectively
using one of the selective tools. Use the
included controls to adjust your image.
CONTRAST
The Contrast Slider provides you with
the ability to affect the contrast of
your image. The contrast algorithm
was designed to prevent any unwanted
color shifts from occurring. Moving
this slider to the left will decrease the
contrast throughout the image, while
moving the slider to the right will
increase contrast.
BRIGHTNESS
The Brightness Slider provides you with
the ability to either brighten or darken
your image without creating unwanted
color shifts. Move this slider to the left
to darken your image, or move the slider
to the right to brighten the image.
Once you are satisfied with the results of
the Contrast / Brightness feature, click
on the OK button. Simply click on the
Cancel button to prevent this feature
from affecting your image.
Auto Levels
Use the Auto Levels feature to enable
Capture NX to analyze your image in
order to determine the correct adjust-
ments to spread the available color
information within your image across
the entire range of tonal possibilities.
While similar to the Auto Contrast
button within the Levels & Curves
dialog, the Auto Levels feature provides
you with additional controls.
Choose between the two different Auto
Levels methods from within the Method
pull-down Menu.
AUTO
Applying the Auto method results in
a redistribution of the individual color
channels, similar to stretching each color
channel within the Levels & Curves, to
the entire range of the histogram.
