Shadow/Highlight
Use the Shadow/Highlight effect to brighten shadowed subjects in a clip or to reduce the highlights. This effect does not apply a global darkening
or lightening of a clip, but rather it adjusts the shadows and highlights independently, based on the surrounding pixels. You can also adjust the
overall contrast of a clip. The default settings are optimized to fix clips with backlighting problems.
Specifies that Adobe Premiere Elements automatically analyzes and corrects highlight and shadow problems stemming from
backlighting issues. This option is selected by default. Deselect it to activate manual controls for shadow and highlight correction.
Lightens the shadows in the clip. This control is active only if you deselect Auto Amounts.
Darkens the highlights in the clip. This control is active only if you deselect Auto Amounts.
Specifies the range of adjacent frames that Adobe Premiere Elements analyzes in order to determine the amount of
correction needed for each frame, relative to its surrounding frames. For example, if you set Temporal Smoothing to 1 second, the frames are
analyzed 1 second before the displayed frame to determine appropriate shadow and highlight adjustments. If you set Temporal Smoothing to 0,
each frame is analyzed independently, without regard for surrounding frames. Temporal Smoothing can result in smoother-looking corrections over
time. This control is active only if you select Auto Amounts.
Specifies that scene changes are ignored when you have enabled Temporal Smoothing.
Specifies the percentage of the effect to apply to the clip.
Expand the More Options category to reveal the following controls:
Specify the range of adjustable tones in the shadows and highlights. Lower values restrict the
adjustable range to only the darkest and lightest regions, respectively. Higher values expand the adjustable range. These controls are useful for
isolating regions to adjust. For example, to lighten a dark area without affecting the midtones, set a low Shadow Tonal Width value so that when
you adjust the Shadow Amount, you are lightening only the darkest areas of a clip.
Specify the size (in pixels) of the area around a pixel that the effect uses to determine whether the pixel
resides in a shadow or a highlight. Generally, this value should roughly equal the size of the subject of interest in your footage.
Specifies the degree of color correction that the effect applies to the adjusted shadows and highlights. The higher the value, the
more saturated the colors become. The more significant the correction that you make to the shadows and highlights, the greater the range of color
correction available.
Tip: If you want to change the color over the whole clip, use the Hue/Saturation effect after applying the Shadow/Highlight effect.
Specifies the degree of contrast that the effect applies to the midtones. Higher values increase the contrast in the midtones
alone, while concurrently darkening the shadows and lightening the highlights.
Specify how much the effect clips the shadows and highlights to the new extreme shadow (level 0) and highlight
(level 255) colors in the clip. Larger values produce greater contrast.

Antialias (Windows only)
The Antialias effect blends the edges between areas of highly contrasting colors. When blended, colors create intermediate shades that make
