Thanks Ro! Thanks Limaze!
When I initially looked at the FFT, I didn't think it would work either. I thought the secret was in cloning away most of the vertical and horizontal lines up to where the little stars appear. It helped in some ways but caused other problems. I couldn't believe the 2 little stars on the horizontal could cause all that grief but cloned them out anyway and voila.

Cheers
Dave

Here's another Neat Image effort. First pass, selected hair, inverted and ran filter. Second pass, added eyes to be protected and ran filter again. Then did some smudging to the skin.

Hi,

FFT was my first try here, but the results I got were a disaster until I saw what Dave managed to do with it!!!!
Thanks Dave for sharing your excellent results and the how-to ....

So I went back to FFT and in attachment 2 is the result I got with it.
To further 'clean' the image I used Neat Image very soft settings on the whole image first, and and the luminosity mask later. (didn't want to soften the image to much...)

I also took snapshots of my corrected Green and Blue Channels (the only ones I touched) during the FFT procedure. (attachment 3 and 4)

Hope this helps...

Thank you Flora!

What a great process when we can collectively work on a problem that results in what you finally achieved. It's no wonder I spend so much time here!

Dave

FFT Filter?

Can someone please lead me to what and where I can get the FFT filter? I have a photo (which I will post for the group to see later) that has some terrible horizontal bands that I am trying to remove. I would like to know more about this filter and where I can get it.

Thanks so much

~Sweet-P~

hello duv, do you also know a source of tutorials about the fft technique? darkening cleary visible "stars" in green channel etc is easy, but are there more "advanced" method for removing slight patterns?

Limaze, I use the good old trial and error method. I hear you though and if I see something, I'll give you a toot.
