Lightroom: Non-linear (luminosity mode) curves/contrast

I really really wish there was an option for curves and contrast to behave as they do in photoshop (and every other program for that matter). When pushing contrast, especially in skin tones, the hue shift that normally occurs does not in Lightroom and I honestly think it looks terrible. No amount of tweaking with HSL fixes it. Lightroom is the one and only program that behaves this way by default. It is the only thing holding me back from switching to Lightroom from Capture One. Aperture has this option (sort of), Lightroom needs it!

Most people like that Lightroom's tone curve works on luminosity only. Some people don't like the fact that things like exposure combined with the default "twisted" profiles change hue, and people have even created "untwisted" profiles to prevent that. You seem to be asking for the exact opposite?

Oh, boy... how can anyone possibly like it? A photographer friend (weddings) c calls these green faces and routinely tries to compensate that with HSL sliders.

No, I'm saying I really don't like how lightroom's tone curve works on luminosity only. For some things it looks good, and technically it makes sense, but especially for skin I really don't like what it does. I just wish there was another option.

...I should clarify, this comes at the end of a pretty long attempt to duplicate what Exposure 3 does in Lightroom. Exposure is pretty much everyone's favorite film emulator, and you cannot get the looks it gets in lightroom because of the luminosity curves and contrast. You can get extremely close with curves in Photoshop and other programs, but not in lightroom. Like I said, no amount of HSL tweaking can fix it. It's a fundamental issue with the way Lightroom handles curves and contrast. Deal breaker for me.

So you want hue shifts when adjusting contrast, right?

In some programs, you have to pay extra to keep hues from shifting when adjusting contrast. (e.g. you have to buy the ColorEfexPro plugin to get the 'Contrast Only' feature (which guarantees no hue shifting when adjusting contrast) in NX2).

I think the contrast in Lightroom works pretty good now, are you suggesting an option to have it work differently, or a separate adjustment? If so, it might help your case to be clearer what you are asking for - I mean Adobe may know what you are talking about, but some of us (who don't use Exposure 3...) are still a little hazy...

Posting some examples would help.

I'm having some trouble following. Is "Exposure 3" this Alien Skin product? Never heard of it before.

You're saying it doesn't work properly in Lightroom because of Lightroom's luminocity-only curve control? Since I haven't used this plugin, I'm not sure what one has to do with the other.

I'm just explaining how I got here, this really had nothing to do with alien skin. I know lots of people like the way lightroom handles curves and contrast, but the the luminosity only thing is not always desirable. For me it's almost never desirable. I want to love lightroom, I really do, it's got so much. All I want is an option for curves to behave how they do in photoshop, hue shifts and all. I personally think the non hue shift curves look unnatural when used on portraits I'm sure many will disagree, I'm sure there's great technical reasons for why lightroom's curves are the"right" way but I just can't bring myself to like them. It's just my preference. I can't imagine it would be a difficult add on.
