Fix Moire Effect In Photoshop
I wanted to show you how to fix, this is something that we encounter pretty much more than most other photographers, is moire. It's a little phenomenon where the pattern that is being collected by the sensor, the frequency kind of matches that of the Bayer pattern on a filter, I believe. If anyone wants to correct that I'm wrong and you get this funky, weird kind of alternating bands of color over textured pieces, like this grate, for example. And, in order to fix that, it's pretty simple, but I'll show you exactly what I did. I'm going to turn these layers off, so we get this ugly pattern again. I'll make a new layer and I'm gonna go again to my color sampling tool, which is Alt right here. And I knew from just being there that the grates were gray. I saw them with my own eyes. Believe me, they were gray. So, I'm gonna sample the handle right here and get a nice gray and I'm gonna take my, I'll use a lasso tool and I'll lasso around this entire grate. Kind of being quick and dirty and...
make a selection out of that. And now I'm gonna take my paintbrush, again, over here, just hit undo to get to it. And I'm going to make a new layer, as I just did, and fill it with that single color. And I actually put that pretty low. And, let's see. The opacity's at 10%, my mistake. So, make sure your opacity is at 100%. Dump that color right in there. And then what we're gonna do is, you're gonna change the blend mode on this layer to Color. And what that leaves you with is a solid gray over our grate and I think that's, obviously, too much. So, I'm gonna kind of clean it up. First, I'm gonna add a layer mask and I'm gonna use a black brush here to kind of brush out the gray on the seats. And then I'm gonna dial back the opacity until it looks good. And, I mean, I think that's all it really needs. We can play with this color a bit too. I'm not have it exactly. I'll go to more of like like this gray here and I'll dump that and see how that looks. And again, blend mode to Color and I'm gonna play with the opacity of the layer until it kind of minimizes that awful banding phenomenon. And then again, make a layer mask and just kind of brush out again. If I was doing this on a job, I'd be extremely detailed with this, but I'm just trying to show you exactly how I do it the quick and dirty way. So, I can get rid of that and there's what we're left with after a little bit of experimenting, but it's the same concept and I'll show you what the layer looks like without any adjustments on it. Let's see. There you go, so we see the layer as it was before. That's why it ended up finished on. And that just kind of cleans those up. Pretty quick and easy.
