Ofnuts:
I tried using curves as you suggested, but I apparently have a manual dexterity problem... doing as I think you wanted me to do is something I don't seem to be able to do, as it requires tiny precise motions of the mouse pointer, which I apparently can't do.
so I dropped back, punted with the levels dialog where I'm able to do something similar (if not the same) to what you suggested and I'm getting pretty good results:
-drag the right-most pointer back to where the histogram goes to zero,
-open the green channel and drag the right pointer back some small amount til the purple disappears or fades, but not so far as to start turning light/white-ish things into faint green things.
-Add in some unsharp mask hacking and occasional other minor tweaks and I have some fairly decent looking images.
(this is a shot of Lake Powell, behind the Glen Canyon Dam in Arizona, circa Aug 1973, taken from the bridge over the canyon just downstream from the dam, early morning sun, facing northward. Asahi Pentax Spotmatic, probably my 200mm fixed-length lens.)
