Blending the Front and Back Images of a Layer
There are two different methods you can use to blend the front and back images of a layer: Basic Blend and
Curve Blend.
Basic Blend is appropriate for layers that do not have a matte component. It allows you to add the front and
back images, and adjust the colour and opacity of the result image. In effect, since you are using the entire
front image, the back image does not influence the result.
NOTE Basic Blend is only available for MBlend nodes. It would not be useful to blend colour images in a composite
in this way.
Curve Blend is suitable for layers that have a matte component. It allows you to use front and back matte
curves to adjust the luminance of the front and back mattes, and also perform logical operations on the
front and back images.
The two methods are mutually exclusiveyou can set the blending in both the Basic Blend and Curve Blend
menus, but it is the menu that is displayed that takes effect.
Basic Blend
Use Basic Blend to adjust the opacity and colour of an MBlend layer that has no matte component. This
results in adding a second defined layer to the first one. You can control the opacity of the second layer.
NOTE You can also use Basic Blend when you have defined a matte in the Matte pipe. In this case, the blending
is applied to the defined matte area only, rather than the entire front image.
To use Basic Blend:
1 Select the MBlend layer by clicking one of the blue boxes to the right of the layer.
The MBlend menu appears and the name of the layer you selected appears in the Layer Name field.
