Again, use a new layer, set the layer to screen, paint the highlights using the airbrush. Play with duplicating the layer and setting it to overlay. However, a better method is to make the glow at render time using a colored spotlight. See my jedi pic at the attached thread. The glow on the character was rendered in poser. The glow on the wall was done using the above method.
