I do all my de-noising outside of Gimp, using either Digikam or a specific tool for the job (ie. Noise Ninja for Linux, which is commercial). For the most part, I've found all noise reduction plugins for Gimp to be lacking, especially for professional photography. The only exception would be GMIC, which has the potential to be an amazing noise reduction tool. It's like the Swiss army knife of Gimp plugins. Specifically, Anisotropic Smoothing in the Enhancement category can generate some outstanding results. Problem is, the options are so numerous and arcane, I can't make heads of tails of them. I've wasted tons of time adjusting options blindly until I was happy with the results... but then I couldn't figure out WHY the settings worked, so I couldn't really reproduce them reliably.

[Gimp-user] eliminating noise at high ISO
My D3000 does a pretty lousy job at 800 and 1600. I've tried playing with some of the tools recommended in Goelker's "GIMP 2.6 for Photographers" but didn't really see any noticeable improvements. Also tried using the wavelet denoise in UFraw. I downloaded a wavelet-denoise plugin and that seems to work a little better. All tools were used on the single RGB layer. Any recommendations would be appreciated (aside from upgrading my camera- LOL) as I have a great but grainy shot of a Racoon at ISO 1600 that I'd love to print. -- Byram (via gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
