How do I know where Sharpening will be applied?

Hello.
I'm really new in CO, so far I think that it's an amazing product. Because of that I'm in the process to migrate all my work made using LR and PS into CO.

One thing that I noted is that I used to use when sharpening an image in LR, a feature of it called MASK slider in Sharpen section. With it, you can create a mask to sharpen an image or part of it. The good thing of this tool is you can hold OPT/ALT key and it shows you where the mask will be applied. For ex., in an landscape you probably don't want to sharpen the blue part of the sky. I guess that in CO this is called THRESHOLD but I really don't know which part of the image it will be affect.

I know that CO was born using different concepts, but may be there is a way to do this that I do not know.

Sorry if I'm not explain myself very well, in that case, let me know.

Regards.

Cristian.

  Here's a way of approaching this in C1. For your landscape image, set the overall level of sharpening using the tool on the details tab to the minimum amount of sharpening you would like to be applied to the whole image. Then you can use a local adjustment to apply more sharpening to selected area, perhaps the foreground. So you would create a local adjustment layer using + on the local adjustment tab. Paint in a mask on the bit you want to have extra sharpening.* The you can increase the sharpening using the slider under the sharpening tool on the local adjustment tab. (Note that you can only increase the amount here. You can't decrease it, and you can't change the radius and the threshold which are set globally for the whole image. If you want to see where you will be applying the extra sharpening, you can press M to see the mask you are painting and M again to hide the mask. (It doesn't disable it, just hides the mask.) Or you can use the option to show the mask only when you are brushing it on.
  
  *If it would be easier, paint a mask on the parts you DON'T want the extra sharpening for and then invert the mask.
  
  Hope that helps.

  Also work the with radius (probably a sub-one setting) for targeting the finer details likely in a landscape. And the threshold slider to decide what is an edge. Threshold may give you something a little bit similar to Lr's masking slider.
  
  A killer feature of Lr is its preview of its sharpening slider effects.

  Hello
  
  Thank you very much BobRockefeller and Ian3 to take time to respond this question.
  It was very helpfully and I'll try that method using a complete mask on the image and treat zones in a independent way.

  With all due respect to the responses given, the question remains unanswered and has been since CO7 at least. To the best of my efforts, the Threshold slider is basically useless. Yes, we can use the layers approach, and that is what we must do. There is no visual way of knowing what the threshold slider can do as far as I can tell and I have yet to hear differently. Yes you can view a file in another program i.e. LR where you have a visual, but that will not apply to the file you have now opened in CO and even if it did, why would you want to have to do that???? I have yet to see an explanation of this slider's purpose or it's usefulness in light of same. In LR it is very useful.
