Compositing is the process of using blending modes to vary the transparency or color interaction of two or more overlapping objects. Blending modes manipulate the color values of overlapping objects. They also add a dimension of control to the opacity effect.
Choosing a blending mode applies it to the entire appearance of selected objects. Objects within a single document or a single layer can have blending modes that differ from other objects within the document or layer.
When objects with different blending modes are grouped, the group's blending mode overrides individual blending modes. Ungrouping the objects restores each object's individual blending mode.
A blending mode contains these elements:
|
Blend color is the color to which the blending mode is applied. |
|
Opacity is the degree of transparency to which the blending mode is applied. |
|
Base color is the color of pixels underneath the blend color. |
|
Result color is the result of the blending mode's effect on the base color.
