Hi zganie
I've just tried "remove moire" in Corel Photo Paint only set on 1 of a possible 10 and it removed it altogether, however there is no such filter in Photoshop , so not sure how to shift it in Photoshop, mabe someone will know of a plugin you could download.

The noise removal plugin for PS called Noiseware eliminates the pattern easily. Also, the Filter>Noise>reduce Noise in PS CS2 and later versions will remove it as well.

If the techniques mentioned above work for you, go for it.

On the other hand, there are other approaches for more stubborn patterns.

If you can rescan, you can try doing two scans with the image rotated 180 degrees in the second, rotate the second one, overlay it on the first, align them, then combine them with blending techniques. There is more info about this approach somewhere on this site.

For more severe patterns, you can use a technique discussed at length on this site. There is a tutorial on it too. Just search for 'FFT' on this site. Most of the discussion refers to a free FFT plugin for photoshop on windows.

If you are using a Mac, you are not as lucky. The only FFT plugin for the Mac costs $800US (part of FoveaPro-a package designed for scientists, not photographers). There is also a free scientific image analysis program called 'ImageJ' that runs on the Mac. It looks challenging to learn but certainly works (there are windows, linux and unix versions too).

I am trying to encourage a plugin programmer to design an equivalent of the free windows plugin for the Mac platform--but without much success so far.

if it were a moire pattern on a print, you could rotate the photo 45 degrees on the scanner bed to get rid of it. noiseware does a pretty good job, on this photo.

Sorry didn't have time yesterday but see the difference between "noiseware" and "remove moire" below (best I could get), as you can see they both do the job, but IMO Corel remove moire leaves you with far more of the detail left.
