Although I've not mastered the technique, I'm now aware of it: the
Blend-If sliders in Photoshop. They permit you to apply effects to
certain tonal ranges, either in the layer you're working on, or the
layer beneath it. A good tool for the inevitable halos that appear,
especially in the upper tonal ranges.
