Lighting Effects effect
The Lighting Effects effect applies lighting effects on a clip with up to five lights to introduce creative lighting effects.
Lighting Effects lets you control lighting properties such as lighting type, direction, intensity, color, lighting center,
and lighting spread. There is also a Bump Layer control to use textures or patterns from other footage to produce
special lighting effects such as a 3D-like surface effect.

Posterize effect
The Posterize effect specifies the number of tonal levels (or brightness values) for each channel in an image and maps
pixels to the closest matching level. For example, if you choose two tonal levels in an RGB image, you get two tones
for red, two tones for green, and two tones for blue. Values range from 2 to 255. Although the results of this effect
are most evident when you reduce the number of gray levels in a grayscale image, Posterize also produces interesting
effects in color images.
Use Level to adjust the number of tonal levels for each channel to which Posterize will map existing colors.
ProcAmp effect
The ProcAmp effect emulates the processing amplifier found on standard video equipment. This effect adjusts the
brightness, contrast, hue, saturation, and split percent of a clip's image.
Shadow/Highlight effect
The Shadow/Highlight effect brightens shadowed subjects in an image and reduces the highlights in an image. This
effect does not apply a global darkening or lightening of an image, but rather adjusts the shadows and highlights
independently, based on the surrounding pixels. You can also adjust the overall contrast of an image. The default
settings are optimized to fix images with backlighting problems.
The Shadow/Highlight effect has the following settings:
Specifies that Adobe Premiere Pro automatically analyzes and corrects highlight and shadow
Auto Amounts
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 image. This control is active only if you deselect Auto Amounts.
Shadow Amount
Darkens the highlights in the image. This control is active only if you deselect Auto Amounts.
Highlight Amount
Specifies the range of adjacent frames that Adobe Premiere Pro analyzes in order to determine
Temporal Smoothing
the amount of correction needed for each frame, relative to its surrounding frames. For example, if you set Temporal
Smoothing to 1 second, Adobe Premiere Pro analyzes the frames 1 second before the displayed frame to determine
appropriate shadow and highlight adjustments. If you set Temporal Smoothing to 0, Adobe Premiere Pro analyzes
each frame 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 Adobe Premiere Pro ignores scene changes when you have enabled Temporal
Scene Detect
Smoothing.
Specifies the percentage of the effect to apply to the image.
