Shadow/Highlight command is suitable for correcting photos with
silhouetted images due to strong backlighting or correcting subjects
that have been slightly washed out because they were too close to
the camera flash. The adjustment is also useful for brightening
areas of shadow in an otherwise well‑lit image. The Shadow/Highlight
command does not simply lighten or darken an image; it lightens
or darkens based on the surrounding pixels (local neighborhood)
in the shadows or highlights. For this reason, there are separate controls
of the shadows and the highlights. The defaults are set to fix images
with backlighting problems. </p>
<p>The Shadow/Highlight command
also has a Midtone Contrast slider, Black Clip option, and White
Clip option for adjusting the overall contrast of the image, and a
Color Correction slider for adjusting saturation.</p>

<dd>Controls (separately for the highlight and shadow values

Amount values may lead to a crossover, where what started as a highlight

</dd><p class="dlseparator"></p><dt class="dlterm">Tonal Width</dt>
<dd>Controls the range of tones in the shadows or highlights
that are modified. Smaller values restrict the adjustments to the
darker regions for shadow correction and the lighter regions for
highlight correction. Larger values increase the range of tones
that are adjusted further into the midtones. For example, at 100%
the shadow tonal width slider affects the shadows the most, the
midtones are partially affected, but the brightest highlights are
not affected. Tonal width varies from image to image. Too large
a value may introduce halos around dark or light edges. The default
settings attempt to reduce these artifacts. Halos may also occur
when the Shadow or Highlight Amount values are too large.<div class="tip"><img src="images/tip_help.png" />Tonal Width is set to 50% by default. If you find
that you are trying to lighten a dark subject but the midtones or
lighter regions are changing too much, try reducing Shadow Tone
Width toward zero so that only the darkest regions are lightened.
If, however, you want to brighten the midtones as well as the shadows,
increase Shadows Tonal Width toward 100%.</div></dd><p class="dlseparator"></p><dt class="dlterm">Radius</dt>
<dd>Controls the size of the local neighborhood around each pixel.
Neighboring pixels are used to determine whether a pixel is in the
shadows or highlights. Moving the slider to the left specifies a
smaller area, and moving it to the right specifies a larger area.
The optimum local neighborhood size depends on the image. It’s best
to experiment with the adjustment. If the radius is too large, the
adjustment tends to brighten (or darken) the whole image rather
than brightening the subject only. It’s best to set the radius to
roughly the size of the subjects of interest in the image. Experiment
with different Radius settings to obtain the best balance between
subject contrast and differential brightening (or darkening) of
the subject compared to the background. </dd><p class="dlseparator"></p><dt class="dlterm">Brightness</dt>
<dd>Adjusts the brightness in a grayscale image. This adjustment
is available only for grayscale images. Moving the Brightness slider
to the left darkens a grayscale image, and moving the slider to
the right lightens a grayscale image.</dd><p class="dlseparator"></p><dt class="dlterm">Midtone Contrast</dt>
<dd>Adjusts the contrast in the midtones. Move the slider to
the left to reduce the contrast and to the right to increase the
contrast. You can also enter a value in the Midtone Contrast box.
A negative value reduces contrast, and a positive value increases
contrast. Increasing midtone contrast produces greater contrast
in the midtones while tending to darken the shadows and lighten
the highlights.</dd><p class="dlseparator"></p><dt class="dlterm">Black Clip And White Clip</dt>
<dd>Specifies how greatly the shadows and highlights are clipped
to the new extreme shadow (level 0) and highlight (level 255) colors in
the image. Larger values produce an image with greater contrast.
Be careful not to make the clipping values too large, because doing
so reduces detail in the shadows or highlights (the intensity values
are clipped and rendered as pure black or pure white). </dd><p class="dlseparator"></p></dl>
