Default Getting rid of Moire patterns

Does anyone have a good technique for getting rid of moire patterns on clothes? If its on a black suit I usually just desaturate and maybe colorize that part but this is on a lighter color. Any ideas?

Hi LT

How did the moire occur in the first place. Was this a scanned photo, or a scanned magazine print?

The best place to deal with moire is BEFORE you load in PS.

It's not a scan, it's a picture taken with a Fuji S2 pro, in RAW format. The fabric on a girl's pants is producing a moire.

I'm not sure what to tell you. Moire has become a generic term for problems.

Adobe's new RAW converter probably has the best tools for dealing with moire before the conversion.

May I suggest that you post this in the FUJI section?

Well, the Fuji SLR section is mostly dead, and besides, the moire pattern problem is not unique to fuji cameras.
I have Photoshop CS and I am quite familiar with the raw converter. What specific tool or adjustment did you have in mind?

Scan the picture tilted, then straighten it out in Photoshop...

Try scanning at a high resolution then down scalling it in PS...

Add more passes on your scanned image...

Put the moire pants on a separete level and run the despecle filter...

Or maybe the Gaussian blur filter...

Just a few guesses...

Hi Lt

Thye problem here is that moire can take so many forms. As I said its become a generic term.

Is the moire noise?

Is it a pattern? What kind of pattern.?

With my D1x I rarely find moire, although noise can be a big problem at higher ISO's

In the the PS RAW converter under advanced functions, there are vignitting dialoge's, noise, ect, ect.

Now once you have the image in PS the only thing I can think of is to mask off the offending area and then blur it a bit - But I'm not the worlds expert with PS, although comfortable with it.

Masking is quite flexible and you can add or subtract from the masked area - You can also stipulate "feathering" of the mask.

You might want to try it and hopefully someone more advanced then I can comment.

Before you start messing in Photoshop view the image 100% or blow up the area with the pattern. The pattern is often produced by the monitor with just the right combination of lines and angles. It won’t be there on a print.

:lol: Try this for size. In Photoshop (I use 7 ), go th channels, select the channel showing the most moire (probably blue), gaussian blur slightly, back to RGB. See if that works.

Let me know
