Question Any hope for this Moiré?

Hello,

This is part of a client supplied image for an ad running in one of the publications I do image retouching for. As you can see there are horrible moirés in the fabric pattern on the sofa.

I've tried just about every technique I could find in the books I have, searching this forum, and looking for other online tutorials. It has my supervisor and I both stumped!

Is there any hope for it? Help?

A smaller version of the file is attached, but if you want to see the full size image, you can get it here: full size image

Thank you!

Re: Any hope for this Moiré?

When I look at this the pattern changes as you change the image size (on both the images you posted). I have also seen this happen on some of my own stuff.

If I go to print one of these type images, usually the pattern does not show up in the print.

So I guess what is happening is that the pattern appears on your screen when the resolution and size of the image match up with the dot pattern of the monitor, when you have the right pattern in the image to begin with.

Not really sure that that theory holds any water, but am always open to any other suggestions.

I was hoping for that too... but not only did we run a print in-house on our 7800, we sent it out to run on Kodak approval... its still there.

The really bad thing about this particular image, is it seems that no matter what you try to do to it, it gets worse.

Re: Any hope for this Moiré?

See if you like this.

I found a section of fabric that didn't have a moiré, then created a pattern out of it. Created a full layer of the pattern and put the couch picture over it, erasing away only what was needed to reveal the pattern below, being careful to keep any areas of detail/edging. Then used dodge/burn to add back in the correct shading to make it look more realistic.

Hello,
First I think for this kind of moire pattern Misterjp technique I think is the best route to go and his retouch was extremely good....

Now the following procedure not sure if you have seen....... but I can see it working for certain kinds of moire pattern... which you can maybe put in your ref list... it specifically for photoshop in mind....

Very good job MisterJP... just wondering have you tried scanning at an angle... say 45 degrees.

Or two scans at different angles then recombining.

Re: Any hope for this Moiré?

I added some grain to break up the moire.

Photo#1 = before
Photo#2 = after

Edit: Tried to get a little better result..
#3 = Hi Pass Filter .1 radius, 2 times,
Ran the median filter on background layer.

Re: Any hope for this Moiré?

Hi PixelHawk,

if I haven't done it yet, welcome to RP!!

Don't know if it will be good enough for print, but, working on your full size image I followed (and tweaked) this great procedure... (thanks again for it, Rô!!! )

... so true ... that's why my attachments are at 100% (which I think is the most important..) and 200% size ... if you view the image at smaller magnifications you'll still see the 'pattern' ...

Let me know if it's ok and if you'd like the exact 'tweaks' I used on your picture.

Re: Any hope for this Moiré?

Wow! Some fabulous responses from all of you! Thank you! I can see that once again, there are multiple ways of achieving the same goal in Photoshop, and I plan on using each of these when the need arises.

Flora, thank you for the welcome... this is a fantastic forum! And yes, if you would be so kind... I'd really appreciate the tweaks you used on the image.

Funny how just as you start to think you're getting pretty good at something, you get humbled by a thing as simple as this.
