Hi there dear colleges!

Once again I came here fo find peace and confort.... meaning help.

I've got a incredible case of moirÃ© 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 moirÃ©. So please can someone explain me how, and if do you think that it will work on this photo?

Tanks.

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 moirÃ© 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.

My Photoshop isn't running, so I can't use the plugin from C1. C1 also has moire suppression built-in, I can run it through there if you like.

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.

When I read "worst case moirÃ© ever" the first thing I thought of was "D70". :)

Oh, so it's a D70 thing?

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.

Can be a real pain in the behinds sometimes.
