Moire?

[Wally]

I have never come across this in one of my photos before.  Is the "tiger print" pattern on this lady's chest moire?  And if so how does one go about improving/removing it?

[Damien Symonds]

Indeed it is.  It can strike at any time!

Is this SOOR, or have you already done some Levels work on it?

Also, do you want assistance with the sweat patch too?

[Wally]

This is with the levels work complete.  Yes the sweat patch was going to be my next question.

[Damien Symonds]

Ok, would you mind temporarily turning off all the levels layers to show me the SOOR?

(including the 100% crop)

[Wally]

Here they are.

It's a teensy bit regrettable, but I think you'll need to start by reducing the texture of the dress in that area.  To do that, add a Dust & Scratches layer at 1/0, then mask to the area of her bust that has the most clear texture.

Then add a new blank layer and use this method to get rid of the sweat stain.

Then use this Channel Mixer layer to fix the moire:

• R 0, +116, 0, +11
• G 0, +100, 0, 0
• B 0, +100, 0, -2

(Make sure you get those numbers in exactly the right order.)

This is my first attempt.  I have a few questions as this is the first time I've ever used a channel mixer layer.  The area where the moire was now has a slight yellowing to it since the channel mixer layer was applied (and masked).  Is this normal?  Which one of your classes would teach me about using the channel mixer?

As always you were correct.  I triple checked them and still has them wrong.  Better?

[Damien Symonds]

It looks good, well done.

[Wally]

Thanks for your help.  Do you have a class that covers the channel mixer?

[Damien Symonds]

Yes, the Channel Mixer Class

But presently I'm overhauling it, so it's not available right now.
