Reducing luminance noise

In the previous exercise we saw that it's pretty easy to eliminate color noise inside of an image. For example, in the case of the Subterranean ventilation.dng file, found inside the 05_for_source folder, all we had to do in order to fix a considerable amount of color noise, this was the before version of the image, all we had to do was raise this color value, here inside the Detail panel to 20, and that took care of everything, it took care of that problem. Luminance noise is trickier. Its not just the matter of adjusting the luminance slider, you also have to fiddle around with a few other options, but it does center on the luminance slider.

Now notice what I am talking about where luminance noise is concerned, we have all this variation going on between these neighboring pixels, where the luminance levels are concerned, and this isn't because this is actual detail, this is magnified noise essentially that we are looking at, detail that was invented out of whole cloth by the camera an...
