Once again I came here fo find peace and confort.... meaning help.
I've got a incredible case of moiré from a few shoots in a wedding. The bad news are that is from the bride mother in law and she wants the photo in the digital album.
This is the photo:
I know that there's some ways to correct moiré. So please can someone explain me how, and if do you think that it will work on this photo?
Hoo, that *is* bad at this resolution. Can yo post a 100% crop of the affected area? Let's see what you've go to deal with. Might also be a good idea to make the full-size original available online somewhere so folks can take a stab at correction.
I have a moire correction plugin for Photoshop that came with C1Pro. I haven't had occasion to use it, but given the quality of Phase One's other sofware, I imagine that it would work quite well.
You can download the demo of C1Pro and get the plug in that way.
Did you by any chance shoot it in NEF?
Do you have Nikon Capture?
If so, run the NEF trough Nikon Capture. Capture is a lot better with moiré correction / demosaic-ing on NEF's than the camera is. Altough this example is pretty extreme.
If you don't have Capture I could run the NEF trough Capture 4.4 or NX to see what happens.

Thank's for the idea. I shoot it in nef and I'll try to pass it though the Capture. I've done this with RSPremium.

Capture should be better by default. If you have Capture 4.x also check Color Moire Reduction under Noise Reduction in Tool Palette 2
Oh, you did shoot in RAW, that helps enormously. I second the idea of sending it through Capture. I've heard good things about its ability to supress moire.
Yes, as far as I know it depends on the strength (lack of it) of the Anti-Aliasing filter. The advantage is more basic sharpness and resolution but it can create problems like this.
I've had some trange situations with bad moiré with my 2 D70. I't intermitent, because in some dificuult patterns it can resolve the detail withought getting confused, and other times it puts lot's of moiré in simple fabrics and clothes.
Wow, I have NEVER seen moire like that... that is wild. What is that outfit made of?
Typically patterns with narrow parallel lines or grids cause the most problems -- to me, that fabric looks like it might be some kind of herringbone pattern.
If you are ever faced with shooting a subject like this, you might try a trick from the offset printing business: place the sensor grid (halftone screen in the old days) at about a 30- or 45-degree angle to the predominant lines in the subject pattern. You'll probably have to loosen up the framing to capture the shot and crop later.
Moire is an interference pattern formed by the interaction of angled lines, so adjusting the relative angle can reduce this interference.
This also applies to scanning, especially if you are scanning something which has already been commercially printed (with halftone dots), like from a magazine; angle the subject 30 degrees to the scanner for (usually) improved results.
