Never more than a tiny bit. It's a matter of developing an eye for histograms,
so I know whether I need to lower
brightness/contrast, and how much, for a given level of LCE. On most images, I
hit it first time, but I've had a lot of
practice.

Select=>Color Range
Fuzziness 27
Minimum:Lab color Luminance: 100 A: 0 B: 0
Maximum:Lab color Luminance: 100 A: 0 B: 0
That's what the Action says, but I don't think you can just put in the color
values in the Color Select box. I think I
selected a pure white with the dropper.
As I recall, I had to try different values. Tighter values of Fuzziness pretty
much never selected anything visible. I
originally developed it and a companion black selector to fill the blown areas
with red and black, so I could see what
was happening in an image.
