Thanks to all who responded with the suggestions.
Attila and John:
Indeed, in PS, one can do curve adjustments, etc.
However, at least in LR3, one can only adjust areas of the curve, not the
points. From Godfrey's response, I guess it became possible in the latest
LR.
The reason I am still on 3.x is because of the compatibility with an XP
computer. It's a complicated chain of dependences, that I am not ready to
break at this point. I'll probably do it soon, but not just yet.
Playing with the luminance of blue is a good idea, thank you, Matthew and
Paul. It can be used in some cases (but not all).
Godfrey and John: adjustment brush is a much more involved tool, since the
combination of the sky and other features is somewhat complicated in some
of the photos.
So, it looks like Tone curve in point mode in the newer LR would be the
best solution.
Rob: I am a bit confused by your suggestion:
My preferred global approach is to apply USM starting at around 25%
with a large radius of 250 pixels or so.
If by USM you mean "unsharp mask" ???), then how would this help?
I don't think I follow your thought here.

Hi All,
I am working on some nature pictures. In these photos there is plenty of
sky (as well as clear water and shores scenary.
Some of those were taken when the sky was a bit hazy.
Boosting up the contrast in LR helps getting rid of that haze.
However, in some of the photos, it makes the rest of the image a bit too
contrasty.
It seems to me that if I could selectively boost up the contrast of the upper
portion of the tone curve, that would do the job better.
Hence my question: what are the options of conveniently (!) boosting up the
contrast of a specific portion of the tone curve without affecting the rest
(in LR, specifically LR 3.x, but that probably doesn't matter much)?
Thank you!
Igor
