So, if I were applying that to say, the blur of a layer, w= hat would be the "distance" variable? I'm stacking several la= yers with Add transfer modes and variable amounts of blur.

The in= verse square law states that intensity is inversely proportional to the squ= are of the distance from the source. Symbolically:
intensity =3D 1 / (distan= ce^2)

Doing a little math, when the distance is 1, the intensity is 1. W= hen the distance is 2, the intensity is 0.25. When the distance is 3, the i= ntensity is 0.111. When the distance is 4, the intensity is 0.0625.

I think this was more of an experiment to see if I c= ould do it myself and understand the math a bit better.=C2=A0
