It's Windows-only, and not a plug-in, but it does a good job.

Well i use Greycstoration and i'm quite happy with itįor linux user there is also a newer version, do not work with gimp 2.5 but works well with 2.4.įrançois Collard Ninja selects several small zones of the image when you choose 'auto profiling'. i have been using neat for some time now but the prob is when there is a lot of noise and no uniform surface. I don't remember from the top of my head, but there are 2 parameters that you should really change, the rest is harmless. GREYCstoration is magic, once you know how to make the enchantments. Neat Image and Noise Ninja use noise samples in order to make a difference between noise and image details (like noise removing algorithms in sound editing software) they don't do a simple blur.įrançois Collard (a group admin) edited this topic ages ago. IMO, Noise Ninja is a little better than Neat Image and sometimes quite miraculous with grain from scanned negatives. The free version of Neatimage is limited to a small size when used as a plug-in (using the PS plugin through gimp) but there is no size restriction for the free standing unit. I hadn't tried dcamnoise before but it looks pretty good. I found GREYCstoration did luminance smoothing OK but left blotchy colour patches. I always just ran it separately then added the output file as a new layer in GIMP so I could restore detail in places if I had to, and to preserve the original EXIF data. Hmm, apparently the neatimage PS plugin works in gimp too with a little fiddling: There are two great plug-ins GREYCstoration /greycstoration/ and dcamnoise /art/DCamnoise-2-for-G.īoth are excellent and useful, it's worth playing around with them to get an understanding of how they work and when one is better than the other. IMO it works better than the Gimp techniques I've tried. There is a free version for non-commercial use, and it works with Wine in Linux.

He has a good tutorial about removing noise in an image. But here too, the result is not very good.ĭo a google search for the gimpguru website. Only the smudge tool seemed to do something substantial. Till now i have tried using the blur, smudge, heal tool. I have a photo which i took from my mobile camera.
