Is there a way to simulate Adobe's Vibrance effect in NX2. I really like the idea of increasing the saturation of the less saturated colors only. The only way I know is selecting color by color, or region by region and doing it, but I wonder if there is no way of selecting all the non saturated colors at once and increasing their saturation.
Normally, I get the look I want using Picture Controls and Quick Fix histogram adjustments. However, I took your post as an interesting challenge. I read a little on Vibrance and did some tests in NX2. Here's what I came up with:
Select adjust/color/color boost Check protect skin tones (don't check if there are no people) Move level slider to 25 Select opacity Change All to Luminance/chrominance Set Luminance to 0 Set Chrominance to 50 Set blend mode to Screen
In my limited testing I found that different pics needed different settings, esp. the blend mode. Sometimes Lighten or Darken worked better than Screen. I saved the edit step as an adjustment labeled Vibrance.
In case your interested, here's my Clarity adjustment:
I find that LCH->Chroma works great for this. You can select a specific color range to increase or decrease saturation (and also broaden or narrow the color range for each selection). Chroma affects saturation without affecting lightness or hue.
Create a new step, select Color->LCH and then select Chroma from the select list. Here is a screenshot of the adjustment dialog:

This is an example as to why a dedicated NX2 forum would be good. Here you see two different approaches, from two different NX2 users, to getting a vibrance effect, and both are totally different.I think both of you did an excellent job at approaching this question.

From a non-user of NX2:
If NX2 has has sharpening with radius and amount adjustments, try sharpening the image with a very high radius and very low amount. This combined with boosting color saturation should mimic vibrance.
Barry yes NX2 does allow radius and amount adjustments when sharpening and uses the same methods that Photoshop uses in LAB space, i.e it sharpens luminance. High Radius Low Amount or HIRALOAM is a technique taught by Dan Margolis in his Professional Photoshop book and his book on LAB. It gives a very different effect than sharpening with Low Radius High Amount sharpening and is used when there are not distinct edges like waves in water. It will tend to give an image a more contoured look and is often used as a step in sharpening faces.

I have both the 2.0 and 3.0 filters for NX2, and neither set has a filter called 'vibrance'. Could you be thinking of the Tonal Contrast filter in 3.0, which is the one I'd thought of when I saw the OP's question?
A very nice one would be NIK's Contrast Color Range filter while applying a negative selection point for the skin. Plain and simple, but very powerful. Never used it thus far - but that will change.
And indeed, this is the kind of topics I like to see more. Capture NX2 together with NIK is a tremendous toolbox which treasures are still largely undiscovered. By taking examples from other applications as a startingpoint you can make great discoveries.
That is also why I am not sure if a dedicated Capture forum would be appropriate - I occasionally sit down with a club fellow behind my PC, experimenting how to imitate tricks in Photoshop and Lightroom in Capture NX2. The poor fellow has no choice as he has invested deeply in Canon, but that only helps me to continue profiting from his CS and LR knowledge.
Maybe a (tool agnostic) forum on 'creative image processing' versus technical image processing (with topics on memory leaks etc.) would be a better idea.
This is one thing where Adobe has the jump on NX2. The vibrance control is a simple and effective way to boost color saturation in an image without affecting skin tones; and without jumping through hoops to do it. All software has strong points and weak points, this is one example where Adobe shines.
You are right - that is exactly what the Color Booster does - but it doesn't provide what Vibrance does: "Adjusts the saturation so that clipping is minimized as colors approach full saturation. This setting changes the saturation of all lower-saturated colors with less effect on the higher-saturated colors. Vibrance also prevents skin tones from becoming oversaturated." (see also http://www.photo-mark.com/notes/2009/jan/19/analyzing-photoshop-vibrance-and-saturation/). Color Booster just saturates everything, with or without skin tones.
I pointed above at NIK's Color Range Contrast filter which may be ess automatic as vibrance (I don't have CS4 or LR), but in comparison gives possibly a bit more control by allowing you to increase color contrast selectively while enhancing overall color contrast in a way that the overall 'color balance' is not overly disturbed - as long as you are modest in applying it. I now also use it as a step before BW conversion (in addition to color points) as it makes you much more in control over color-to-BW conversion.
Which is why I add the Opacity adjustments in my Vibrance simulator. Also, using the LCH method, you can select which colors are boosted and which ones are not, including skin tones. Opacity settings can be adjusted in LCH as well. And I don't think "protect skin tones" can be turned off in Adobe's Vibrance, not sure though.
