This is a simple pixel processor node that combines two curvature maps. It hasn't been tested extensively but seems to produce more accurate results than the AddSub blending mode (blend node). The two maps which are combined should keep their relative look without boosting the foreground.
Edit: Version 1 has some pixelation/artifact issues. A new one is pending approval that resolves these.
