Replacing Sky with Layer Mask
So the next thing I wanna look after, is I want to get rid of that sky. So, I am going to do what we were doing yesterday. Well, the first thing I'm gonna to do is I'm gonna to find a sky image that I like. So, I'm gonna go here, and let's pick one. Do I like that one? I think I need something more horizon line. That one's better. I like this one, this one's cool. So double clicking it. I'm probably gonna make it just a little bit brighter. It's a little bit dark. Just gonna bring up the exposure a tiny little bit. I'm not going to worry about bringing up any ... Contrast, or anything like that. Just leave it alone. Open Image. Command + A, or Control + A. Select All, Copy, Control + C, oops. Aww man, where'd it go? Control + Shift + V, paste. So I'm going to throw this blending mode of the clouds on multiply, same as I did yesterday. Gonna hit V, which is gonna move my background around, and see how we have this nice horizon line coming along here? Because I shot it pretty close to th...
e same angle. And there's enough going on here. So I'm going to create a luminosity mask, like we did yesterday, when we were using channels. So, first thing I'm gonna do is I'm gonna create a curves layer, 'cause I just wanna extract the sky. So I'm going to bring that up, and bring this down. So I'm just creating enough contrast. And hopefully I'm gonna get like a relatively clean cut on the trees. 'Cause like I said, we don't... You guys have seen how to do trees and cutting all that stuff out. So, I'm going to go to my channels. Red channel looks like that. Green channel looks like that. Blue channel looks like that. So I'm gonna try to, I'm picking the channel that's giving me the most black along this horizon line. I'm gonna hold Control, which is going to bring up that square. Gonna go to Layers, I'm gonna go to my sky layer, and I have my dancing ants, so I'm just gonna click on the mask. I'm gonna get rid of that curves layer. And so of course this isn't going to be totally perfect. I'm gonna hold Alt on my model. Sorry, Alt + Control on the model. I'm gonna go to my brush, and I'm going to invert my selection, Control + Shift + I, and I think that'll get me where I need to be. Oh no, damn it! See there's 50% chance right of getting it right, remember I was saying this? This is one of those things. Make sure we're clicking on the layer mask. There we go. Okay select that, and now I just have to clean up ... All this stuff here. So, I'm using far too soft of a brush, and I'm gonna use that dodge and burn technique here. Actually gonna lighten this up along the horizon line a little bit, whoops. Nice and low ... Too much. So remember the things that are further away, have less information. Alrighty. Now, I'm going to hold Alt, click on this, and see how we're doing here along the horizon line. So I'm going to go back to that dodge and burn technique, and I don't remember which retoucher it was. It could've been Glenn Duis, who's out of the UK. He does really nice work in retouching. It totally could've been him, but I don't remember who it was who showed me. It was just like some random YouTube video, so I cannot take credit for figuring this out. It was definitely on the internet. So, we have a little bit of haloing going on here. This grass, like these foresty trees and stuff like that, I probably would spend a lot of time going in and cleaning it up. We don't have time for that today (laughs). I don't wanna do that to you. So, I am just gonna take my brush, nice and small, and I'm gonna bring over some of this sky into her hair because we can, and it's going to look a lot more realistic. So, I've got some malfunctions in her mask going on here. Oops. Here we go.
