Blending mode descriptions
In the following descriptions, these terms are used:
• The source color is the color of the layer or paint stroke to which the blending mode is applied.
• The underlying color is the color of the composited layers below the source layer or paint stroke in the layer stacking
order in the Timeline panel.
• The result color is the output of the blending operation; the color of the composite.
Normal The result color is the source color. This mode ignores the underlying color. Normal is the default mode.
Dissolve The result color for each pixel is either the source color or the underlying color. The probability that the result
color is the source color depends on the opacity of the source. If opacity of the source is 100%, then the result color is
the source color. If opacity of the source is 0%, then the result color is the underlying color.
Darken Each result color channel value is the lower (darker) of the source color channel value and the corresponding
underlying color channel value.
Multiply For each color channel, multiplies source color channel value with underlying color channel value and
divides by maximum value for 8-bpc, 16-bpc, or 32-bpc pixels, depending on the color depth of the project. The result
color is never brighter than the original. If either input color is black, the result color is black. If either input color is
white, the result color is the other input color. This blending mode simulates drawing with multiple marking pens on
paper or placing multiple gels in front of a light. When blending with a color other than black or white, each layer or
paint stroke with this blending mode results in a darker color.
Color Burn The result color is a darkening of the source color to reflect the underlying layer color by increasing the
contrast. Pure white in the original layer does not change the underlying color.
Linear Burn The result color is a darkening of the source color to reflect the underlying color. Pure white produces no
change.
Darker Color Each result pixel is the color of darker of the source color value and the corresponding underlying color
value. Darker Color is similar to Darken, but Darker Color does not operate on individual color channels.
Linear Dodge (Add) Each result color channel value is the sum of the corresponding color channel values of the source
color and underlying color. The result color is never darker than either input color.
Lighten Each result color channel value is the higher (lighter) of the source color channel value and the corresponding
underlying color channel value.
Screen Multiplies the complements of the channel values, and then takes the complement of the result. The result
color is never darker than either input color. Using the Screen mode is similar to projecting multiple photographic
slides simultaneously onto a single screen.
