I want to add two clips together by blending them. but the layer-command normalizes the lightness. I want the lightness increasing when adding two clips together.

In the Moment I am using this:
a=????
b=????
c=subtract(converttorgb32(a),invert(converttorgb32(b),"RGBA"))

but this is not very fast since there are two colorspace conversions and one inversion....

is there another way to solve it?
