Lesson Info

Remove Moire Patterns

in this session, we're gonna cover advanced retouching in a previous lesson. That's part of the complete guide. We covered retouching essentials, and that's not always gonna address everything you got to do. So in this session, we're going to get much more deep into retouching and let's dive right in. The first thing I'm gonna do is show you how to get rid of moray patterns. Moray patterns happened when you photograph something that has a regular pattern to it, like the weave of fabric. You're photographing that with the camera that's using a grid of pixels, and it's kind of like having two grids that don't perfectly align. I don't know if you've ever seen it before, but if you take the screen that you might find in a screen door and take two pieces of it, put it one right on top of the other and then rotate them slightly. A lot of people have seen that effect, but if you do see it, you get a weird interference patterns between the two screens. Well, the same thing happens when you tak...

e a camera that's capturing a grid of pixels, and you pointed out a grid of fabric or something, you can get a pattern. Let me show you what one looks like. If you look closely at this, you see these odd colors that are in here in this pattern well. To avoid that camera manufacturers put a filter in front of the camera sensor that actually softens the image slightly, Uh, and that prevents this from happening. But because it softens the image, oftentimes manufacturers will create two versions of a camera, one that has that filter in front of the sensor and one that does not. So those people that shoot things like landscapes, which you don't find regular patterns and nature. They could use the version without the filter. They'll get a sharper picture. But then those people would do shoot man made objects. Specially fabrics would get the version of the camera with the filter. Sometimes it's called an anti alias ing filter, but there are other names for it. And so this is what it would look like if you might choose one of those cameras without the filter in front of it and use it on fabric. So let's figure out how to fix that. I'm gonna fix it using adobe camera raw. Now this is a J peg file. So fire to just double click on it. It would open it all the way into photo shop, and we can access camera raw from the filter menu in photo shop. But I'm gonna go appear to the file menu in Bridge and choose opening camera. Now, in Kameron, we're not gonna be able to fix us with the normal adjustment sliders that are found in the right side of my screen. Instead, I'll have to go to the top of my screen where I find a bunch of tools up there. You're gonna find two different paintbrush tools we want the one that doesn't have the dots around it. That's the spot removal tool. We want this one. It's called the adjustment brush. When you choose the adjustment brush on the right side of your screen, you're going to get sliders that look a lot like the normal ones you have there when you're just adjusting a picture. But in this case, we're gonna brush these changes into the image. So if I move one of these sliders right now, I'm not going to see any change in the image at all because I need to first paint within the image. Uh, So what I'm gonna deal here is there's a slider called more ray reduction, and that slider is not found in any other areas off camera or and photo shop. And so it's unique to this tool. I'm gonna crank it up a size. It goes just so I can see something when I'm painting on my picture. Then after I'm done painting, we can adjust the amount to make sure it's the lowest amount that really tackles the job. So I'll zoom up here so even more better. See this, and I'm just gonna start painting now. When I do this, I want to make sure that down here near the bottom, the choice called Auto Mask is turned off because auto mask tries to limit where I can paint. And sometimes it might limit me to only painting on these areas that are colorful, and we need that to paint across the whole area. But the thing you want to be careful of is when you're painting here to correct for this more. A pattern is that if the object that has the Marais pattern in it touches another object that is dramatically different in color. That's where you want to paint a minimal amount, because this is blurring the color transitions in a picture. So if I get up here at the top and I see where this outfit stops in the red cherry sitting in begins do you see how the color of the red chair has transferred over to his outfit? And that's because of this choice called the Fringe. Before I fix that, I'm gonna look down here at the main portion of the fabric and I'm gonna adjust the amount setting for more a reduction. I'm gonna bring it all the way down to zero, and then I'll slowly bring it up and try to find the lowest setting that really tackles the job. And I think somewhere right around there is fine, because now I have a more accurate idea of how big of a problem I have up here, where those colors are blending together. If you watch that, I ended up with a setting of, I can't even read that it's either or 66 but if I continue bring it higher, you'd see that that color blends even more shoes undo to get back down. Well, up here at the top above the sliders is a choice called erase E. And if I have that set to erase that probably want feathering turned up a bit so that I get a soft edged brush and I'm just gonna try to get it off of the edge of the fabric so I don't get the color from the chair blending in now we might see some of the more a pattern appear in that area. If I do, I just got to choose a smaller brush and maybe lower the ah slider a bit when I painted in. Ah, but most the time. You can remove it from areas where there's a transition between two distinctly different colors because this moray reduction is gonna blend colors together. And that's how it attempts to get rid of the Moraine. Now, to show a before and after all I'm gonna do is hit the delete key. The delete key is going to remove this little adjustment pin that's here and that all type command Z to undo its controls and windows and so you can see before and after I'm gonna click done there
