Working with Lights
261
Scale Multiply A useful variation of Multiply that produces a brighter image than the standard
Multiply. This is often the most realistic Apply Mode for light effects.
Scale Screen A useful variation of Screen that produces a darker and less washed-out image
than the standard Screen.
Difference X 2 A variation of Difference that produces a more intense effect than the standard
Difference. The enhanced difference modes are particularly effective in creating
glows with the Blur effects.
Difference X 4 A variation of Difference that produces an even more intense effect than
Difference X 2. The enhanced difference modes are particularly effective in
creating glows with the Blur effects.
Add Includes the light or filtered output with the source. The resulting color values are
clipped at white.
Subtract Removes the light or effect from the source. This can produce intense and
unpredictable colors and make the image appear noisy.
Overlay Puts the light or effect over the source. The result is brighter than the result of
Multiply and darker than the result of Screen.
Soft Light Simulates shining a diffuse light (whose color is the light color or filtered output)
on the source image. Most of the detail in the final output comes from the source
image.
Hard Light Simulates shining a harsh light (whose color is the light color or filtered output)
on the source image. The source image and the light or filtered output contribute
roughly equal amounts of detail to the final output.
Hue Creates a result color for each pixel that takes its Hue value from the light color or
filtered output and takes the Lightness and Saturation values from the source
image.
Saturation Takes the Saturation of each pixel from the light color or filtered output and takes
the Lightness and Hue from the source image.
Color Takes the Color for each pixel from the light color or filtered output and takes the
Lightness from the source image.
Luminosity Takes the Luminosity for each pixel from the light color or filtered output and its
Color from the source image.
Transparency Used in Light filters and other lighting effects. Increases transparency in lit
regions.
Opacity Used in Light filters and other lighting effects. Increases opacity in lit regions. If
the image is fully opaque, Opacity has no effect.
