ACR 6.5 and earlier supporting Nikon D7000 are introducing a massive amount of noise in underexposed areas. Enclosed files show jpg captures the same portion of an ISO 100 D7000 NEF file seen at 4X,one file is from ViewNX2, the other three are from ACR at zero sharpening, standard 25 sharpening, 100 sharp with no mask, and 100 sharp masked.

Could you please post the raw file (or if you don't wish to post publicly, you can send via YouSendIt or similar service to

In the meantime, I just revisited my D7000 images here and honestly don't see the issues here. My main comment is that setting sharpening to 100 without luminance NR is going to severely extract / bring out whatever noise/texture there is in the image data. I know you did this just to highlight the differences, but ultimately I suggest using the tool settings that will make the image look its best, rather than look its worst! ;-)
