I have discovered that I can use Colors/Levels to accomplish what I need.
I brought the high Input levels to about 170 which lightened the trough color, the Low input levels to 41 which darkened the crests, and moved the gama to 0.74 which further defined the finger print.
If you have other suggestions I'd like to hear them.
