We can use a Camera Raw adjustment brush in order to paint in different types of corrections. We can use it to paint away noise or color fringing or to paint away moire pattern like we have here in this photograph. If you double-click the Zoom tool to take this image to 100%, you'll notice that there's this interesting pattern all across the photograph. This often happens in digital capture when you're capturing images of textiles or clothing like this, sometimes these patterns will appear. Whether you want to remove noise or defringing or moire pattern The technique is exactly the same, and here's how we do it.
Go ahead and select the adjustment brush by clicking on the adjustment brush icon above. Next, in the adjustment brush panel you want to scroll down to this area where we have a few sliders which allow us to reduce noise or reduce the murray pattern or to defringe the image and get rid of color fringing. Here what I want to do is increase the murray reduction, so we'll click and drag this all the way to 100... Next, let's go down to our brush settings. We'll increase the flow so we can paint this in at full intensity, or the full amount in one brush stroke, and then this brush actually will work pretty well.
All that we need to do is simply click and paint across the photograph. Now if we need to limit this to certain areas, notice that as I paint across this, it's affecting this background over here. What we'll want to do is go ahead and deselect this, or delete this. I'll click on this and press the Delete or Backspace key. And then go to the option where we can turn on Auto Mask. Now when I click and paint across that area, notice how it's not affecting the background. Now once you get away from the edges, turn Auto Mask off. Because in here it works a little bit better. If you have Auto Mask off as you start to paint across the garment.
Also as you're making the adjustment, you may want to experiment with the slider amount. Here as I drag this down, what we'll see is a little bit more of the moire pattern comes back, now we see it in full intensity and it changes in different ways. And different moire patterns will need a different amount in regards to remove it. In this one I think full 100 there works well. And again all that we need to do is to paint across the image and make our way through our photograph. Now here I don't think I need to show you all of the details of working on the edges. Because by now, you get the point that if you're going to work on the edges turn on auto mask. If you aren't, turn it off.
Alright. Well let's look at the area that we worked on. Here if I click on the preview check-box you can see the before, and then click again, andnow you can see the after. An keep in mind, you can paint away moire patterns or noise. So if you have an issue with your image where you have some noise or you have a pattern like this. Experiment with those sliders because they can help you to selectively brush or paint away those problems.
