What about sharpening? Did you sharpen the image a lot?
If you blow things up to 3:1, and you have a lot of sharpening, this could easily happen.
If you turn off the sharpening temporarily, and view the image at 1:1, how does it look?
By the way, why are you examining the photo at 3:1 anyway?
upload the DNG with all your edits to Dropbox so others can see EXACTLY what is going on. Thats the easiest way to get answers to the problem.
I think it's sharpening combined with noise reduction and just bad image noise. I was looking at it in 3:1 to try and see what the heck was going on cause it looked like splattered black paint all over. I might have had the ISO too high or something and the edits are just bringing it out. It just seemed like LR was amplifying it no matter what I did. Thanks for the responses.
In my view, 3:1 (and any other magnification greater than 1:1) is useful only for making very precise local adjustments.
If you just want to view the quality of the image, anything above 1:1 will cause artifacts, don't go higher than 1:1.
