Here is my conversion of Imaging Resource Nikon D800 ISO 3200 NR0
http://www.flickr.com/photos/fineart48/8447544957/sizes/o/in/photostream/

The full size image will be available until the end of March when flickr ends its free Christmas gift.

Download the nef, compare your own conversion in C1, DxO, LR, Photoshop (in case I didn't answer your PS question with ACR).

Bob's LR version a few posts up is covered in black pepper. Was that in the original scene? No, its an artifact that increases perceived sharpness.

My version has a faint random color noise still in it. It is so light it is not objectionable from ISO3200.
