The dpreview forum user “Morepix” found something really interesting about the GH2:”
1) The NR +2 shot had less noise and slightly less fine detail than the NR 0 shot.
2) I ran Topaz DeNoise on the NR 0 shot and compared the NR +2 image OOC. By comparison, the NR 0 shot with Topaz processing was better in every respect than the one with in-camera NR.
3) For some reason, the NR +2 shot showed chroma noise (blue) which the NR 0 shot did not.
4) My conclusion: Don’t use in-camera NR on RAW images. But if you want to clean up noise at higher ISO, Topaz does the best job I know of.”
