Apply Mode Menu
Many effects use Apply Modes to apply the filtered output (or light or some other aspect of
the effect) to the source image. Apply Modes control the blending of the two images, giving
the effects many additional creative possibilities.
In OpenGL mode, you cannot see non-accelerated objects when you use the on-screen
interactors. Non-accelerated objects include apply modes. As you adjust the interactors, the
Composite window displays the message “Accelerated Draft Preview” to let you know that
you are not seeing all objects. When you release the mouse button, the Composite window
displays all objects. If you need to see all objects, press the Alt or Option key while you
interact.
Apply Mode Effect
Normal Applies the light or filter directly to the source image and the filtered pixels
replace the source pixels.
Lighten Compares the color channel values in the original pixels and in filtered pixels and
chooses the lighter (higher) value for each channel in each pixel. If you apply a
pure red pixel to a pure blue pixel, the result is pure magenta.
Darken Compares the color channel values in the original pixels and in filtered pixels,
and chooses the darker (lower) value for each channel in each pixel. If you apply
a pure red pixel to a pure blue pixel, the result is black.
Multiply Applies the light or effect to the source as if it were a transparency placed over
the source. The resulting image is darker than either. If a pure red pixel is applied
to a pure blue pixel, the result is black. If a 50% gray pixel is applied to another
50% gray pixel, the result is 25% gray.
Screen Applies the light or effect to the source as if a photographic double image was
taken of the light or effect and the source. The resulting image is lighter than
either the light or effect or the source. If you apply a pure red pixel to a pure blue
pixel with Screen, the result is magenta. If a 50% gray pixel is applied to another
50% gray pixel with Screen, the result is 75% gray.
Difference Outputs the difference between the light or filtered color and the source color for
each channel. Difference modes can produce some very striking colors and create
glow effects when used with Blurs. Difference modes can also exacerbate noise in
video sources. Difference can generate non-Color Safe output.
Lighter Uses the lighter of the source and filtered colors for each pixel for all channels. If
a dark green pixel is composited with light red, the result is light red.
Darker Uses the darker of the source and light or filtered colors for each pixel for all
channels. If a dark green pixel is applied to a light red pixel, the result is dark
green.
