Image Control effects
Black & White effect
The Black & White effect converts any color clip to grayscale; that is, colors appear as shades of gray. You cannot
keyframe this effect.
Change Color effect
The Change Color effect adjusts the hue, saturation, and lightness of a range of colors. Choose the range by speci-
fying a base color and similarity values. The similarity can be an RGB similarity, a hue similarity, or a chroma
similarity.
Adjust the following controls for the Change Color effect:
View
Specifies what to view in the composition. Corrected Layer shows the results of the Change Color effect. Color
Correction Mask shows the areas of the layer that will be changed. White areas in the color correction mask are trans-
formed the most, and dark areas are transformed the least.
Hue Transform
Specifies the amount, in degrees, to adjust the hue of the selected colors.
Lightness Transform
Specifies the amount to increase or decrease the lightness of the selected colors. Positive values
brighten the selected regions; negative values darken them.
Saturation Transform
Specifies the amount to increase or decrease the saturation of the selected colors. Positive
values saturate the selected regions (moving toward pure color); negative values desaturate the selected regions
(moving toward gray).
Color To Change
Specifies the color to be changed. Matching Tolerance and Matching Softness both use this color
as a target for building the color correction mask.
Matching Tolerance
Specifies the degree of color matching before the color is affected by the color correction. With
low tolerances, only colors very similar to the change color are added to the color correction mask. Larger tolerances
add more of the image to the color correction mask.
Matching Softness
Specifies the softness of the color correction. This control does not always soften the color
correction mask geometrically, but it affects the severity of the color correction for regions similar to the base color.
Match Colors
Specifies the criterion for determining the similarity of two colors:
•
RGB
Uses the red, green, and blue components.
•
Hue
Matches colors based on hue. For example, bright red, light pink, and burgundy have similar hue values (a
hue of red, but differing values of saturation and lightness).
•
Chroma
Uses the two chromatic components to determine similarity, ignoring brightness. Chroma matching is
therefore sensitive to saturation and hue differences, but not to lightness differences.
Invert Color Correction Mask
Inverts the mask that determines which colors to affect. If selected, all colors will be
color-corrected, except those selected by using Color to Change and matching controls.
Change To Color effect
The Change To Color effect changes a color you select in an image to another color using hue, lightness, and
saturation (HLS) values. Perform color changes either by transforming or interpolating into the new color. This filter
is useful for quickly changing one selected color to another, while leaving other colors in the image unaffected.
