Reducing luminance noise

I've gone ahead and saved my changes as Color noise defeated.psd, so called because we did manage to utterly and completely defeat the color noise inside this image. But we've still got lots of luminance noise left over. It's found inside the 16_smooth folder. In this exercise, we're going to attack the luminance noise globally across the entire image. Then in the next exercise, we'll relegate our modifications to just the shadows. So, what I'd like you to do is make sure the color noise layer is selected, then press Ctrl+Alt+J or Command+Option+J on the Mac. I'm going to call this duplicate layer lum noise, like so. Then I'll click OK. Notice I am working from that color noise layer. I'm just keeping the original image in the background in case I want to refer to it later. So don't duplicate the background image in other words, duplicate color noise to build on it. So now we've got a luminance noise layer, the last filter we applied was Reduce Noise.
