Originally posted by millmeister Thank you for your quick replies. I find that I have to bump up the exposure in Lightroom for many of my GR images - not sure if this would bring out noise...
Here is a crop from the 2nd image.

And from the final image
OK, I see it a little clearer now. Again, I think this is a low level of noise... pixel-peeping at 100%, it's noticeable, but at even 50% viewing size, it's irrelevant.
My preset for all photos imported into Lightroom is as follows:
Sharpening:
Amount 50
Radius 0.7
Detail 25
Masking 50
Noise Reduction:
Luminance 25
Detail 75
Contrast 0
Color 25
Detail 50
Smoothness 50
If it's a low ISO shot, I will usually tweak the Noise Reduction Luminance down - sometimes all the way to zero. I rarely go above 25, choosing to keep a good level of detail and accept whatever noise is still present. If it's a fairly noisy shot, I will tweak the Masking up to where only the very outlines of objects are being sharpened - which could mean a setting of 80 - 90.
With these settings, the size I can realistically view or print an image at is then dictated by any remaining noise, and whether-or-not it is appropriate to the image in question.
With your images, note that if you are accepting default sharpening settings, Lightroom applies an Amount of 25 with Masking at 0 - which means everything is indiscriminately sharpened, including noise. Setting the Masking to 50 or 60 will reduce this effect significantly, and may be all you need to do to reduce what little noise you're seeing.
Hope this helps.
