In this installment of the Photoshop Lightroom 4 Essentials series, author and teacher Chris Orwig guides photographers through the process of improving images with creative color, sharpening, and other effects in the Lightroom Develop module. The course covers each of the tools and features in the Develop module, and shows how to perform basic adjustments, such as exposure enhancement; how to improve image quality through noise reduction and clarity adjustments; how to apply creative effects, such as split toning and vignettes; and how to perform advanced tasks, such as correcting for lens distortion. Exercise files are included with the course.
This image has a common problem; it's called moire pattern. Well, what is a moire pattern? Well, the term moire is actually a French word and it originates from a type of a textile. Sometimes it was silk, cotton or synthetic fiber that had sort of a kind of rippled or watery appearance. With this image, you can see that. There are these strange little ripples or kind of watery appearance to this image. In photography, moire happens as a result of digital capture or of scanning an image, and it's an undesired artifact.
These ripples or this appearance, they weren't part of the jacket. This was added when the jacket was photographed. So let's take a look at how we can remove that pattern there. We can do this with the Adjustment brush. If you click on the Adjustment brush, you'll notice at the base, we have a few options for Moire. Click and drag this to the right to minimize that moire pattern or drag it all the way up to try to remove it. In other words, the more you move this to the right, the stronger the moire removal will be. Next, we want to set up our brush. Typically, you want a brush flow which is really high, and you want to turn Auto Mask off. That doesn't work very well as it gets kind of hung up on the stitching or the different edges of the fabric.
Okay, well now that that's dialed in, I'll go ahead and simply click and drag and you can see that as I paint across this image, even in different areas, you can see how we're able to a pretty successfully remove or reduce this moire pattern. Now it's rare that this will be completely perfect and that the fabric will look like it never had any sort of a pattern, but it does really help out, And this can really speed up your workflow to do this in this raw context, because there's nothing to save or to render. And previously, in regards to moving this pattern, you had to go to Photoshop.
Now we can do this here in Lightroom, which is great. The other thing that you may notice is that it might subtly change the color of the jacket, yet it's hard to discern, right, because the moire pattern has a color in it. So as you kind of work on your garment, whatever it is, just pay attention to that. And you may need to experiment with perhaps boosting your color a little bit, and sometimes by doing that, you can bring back some of that natural vibrance or the color of the fabric. And again, other times you may not need to do this at all, but just experiment a little bit with that and you can see how you can really swing it hard.
Sometimes it's just a few points, you know, that bring that back to its more natural color. Of course, when you're working with garments and whatnot, you want this to be accurate. So that's why I'm trying to say be careful with your modifications in regards to color. But I also have to point it out, because I've noticed it as I've started to work on a few photographs. Well, after you gotten through your image, really it's just going to be about making it all the way around. On the edges, it can be a little bit tricky. One of things that I found to be helpful is when you get to edges, to turn Auto Mask on and then go straight across those, because you don't want this moire pattern removal to happen on your background or to tweak the background out at all, and then once you finish that edge work, we'll then turn Auto Mask back off and then just keep working on the middle area.
And you can see here, we can make some pretty quick progress in regards to what could have been a tricky problem.
