Automatically Align Layers in Adobe Photoshop CC
Hi there in this video, we're going to look at aligning images. Why am I doing it in this case I photographed my desk and I need the exposure level for my desk so I can see all my weird sound boards that I use to help make the sound on this microphone nicer. But because of that exposure level, I can't see anything on the screen. So I had to change my exposure so I can see the screen, but then the backgrounds too dark. What do I do? I mask one out and blend them together. But because they don't align, I shot these handheld, you can see they don't line up. I'll show you how in this exercise how to magically line them up. So they're perfect with a click of a button and we can mask out the lower exposure with the higher exposure and the world is a beautiful place. Alright, let's get started. Alright, so there's two ways of doing this. There's the caveman way which will do first. Okay, so we're going to go to file, open, open up the auto align one and two and then I'll show you another way.
Both ways are useful. This one here's got my low exposure for my screen and this one's got my high exposure and all I'm going to do is go select all copy, move to this one and paste it so we've got them on top of each other but they don't line up because I was hand holding this and while I adjusted my exposure it. We're good around. So the auto align feature is select the top one, hold shift, click the last one. We're just doing it with two. You can do it with 1000. Actually, probably not, Photoshop would freak out, but you can do it with 10 or 100. Maybe select all the images you want to align, Go up to edit and there's one down here called auto. Align layers. Leave it at auto, seems to always work at auto. Let's click OK, magically turn the top one off the one underneath. You can see the screens lined up. Perfect. Now we'll mask these two to join them up in a second. I want to show you the other way. So there's the Caveman way and if there's just a couple of images, that's what you need to do. There's another way under file, let's go to scripts and we looked at this earlier on. Remember we looked at loading lots of stuff into a stack. The cool thing about it is they want to load auto align one and two but let's say there is 100. You definitely want to use this automatic feature. Okay, what do align? But also attempt to align them as well. So it's just going to do both processes in one go. It's going to put them all into one file instead of our copy and paste and it's going to try and align them. Kick back, relax. So with just two images, it doesn't really matter which way you go. But with loads of them, it's easier using that script. Now we're using it for exposure levels. It could just be that you have to kind of move around to get the entire front of a building, let's say. Or instead of doing exposure, you're doing kind of like focal length, you're trying to get different kind of focuses along however way you got here. What I need to do is I need to, I'm gonna put this one at the top um, the dark one and I'm going to grab my because what I want to do is actually have the screen, which I can see in this one, but it's too dark back here appear on this image because this one I can see all the background. So I need to combine them to, so with auto align to selected, I'm going to grab my quick selection tool, I'm going to drag a box around here. Pretty good job I'm going to click in here as well. Did a pretty good job. I'm going to go in there's a little bit here that probably needs a little bit of love. So I'm holding down my option key on a Mac OK on a pc just to kind of fix that up. You could use the lasso tool, The polygonal lasso tool, which has a straight edge, however you do selection. I'm going to add a mask and hey presto kind of both combined, the top one is just the screens. This bottom one here kind of fills out the outside. This top one here. What I might do that's it. That's the end of the tutorial. I'm just going to go through now and show you what I do. When I'm trying to blend the two. I'm going to add levels just to the little arrow. This is just to the layer underneath and now I'm going to kind of try and make it look more believable that were too dark, there's too much details and just kind of finding fine tuning what looks real but still legible. Whereas before member totally eligible, exact same screen, different exposure. I can see more. All right. A couple of last little things I want to do to touch it up but you can go now. This is just me missing about to fix this up. So the easy way would be to grab the crop tool and just kind of like shrinking in their crop. All those kind of transparent pixels out and nobody would know except for that. But, but let's experiment with our cool new tools. I'm going to use the lasso tool like you saw me earlier on using the magic wand tool to grab the edges over here and you probably noticed little white bits appeared in the corner and I kind of ignored it. I shouldn't have come here to repent and show you a better way we're going to use the lasso tool. Okay, the polygonal lasso tool, which is the straight edge version and I'm going to draw. I'm just gonna kind of manually do it. So I'm gonna click once, click twice and I'm making sure I overlap it in a reasonable amount, click once, come all the way back to the beginning and when it gets close to the beginning, you see that little circle appears. That means it's a complete selection now to add to the selection. I'm going to hold down the shift key. I'm going to maybe start down here once you've started adding, you can let go of shift because if you don't really wants to do straight lines, so just shift to get it going, okay, click around here, we'll do it one more time. It's a bit of a weird one, that one. So shift to get going, it's gonna click once, then let go of shift. So it is adding, but it's not trying to do straight lines, you can see how overlapping I am there. Um shift, get started, any which way you like to do a selection. Okay, And then we're going to go to edit fill and I have no idea how good or bad this is going to be. Let's just see Not bad ish a pretty good job though. Like that's pretty crazy. Like my white board has now just got magically bigger. It's reusing some of the numbers. My microphone got a little bigger. The desk is not too bad. It's a little bit weird perspective. This is good. Something weird's happening down here, the blanket that I've got pinned to my white board. Why? Because if I don't that whiteboard somehow vibrates so on the microphone instead of me sounding crystal clear, I sound like I'm recording in the like bathroom. Alright, I missed a bit there. Get the idea. The last thing I want to do is maybe the edges here is a little bit white, you can kind of see it coming through here. The cool thing. Remember we've got our sweet new trick when we slept on the mask, select and mask. And what I'm gonna do is I'm going to shift the edge and we've always gone in, okay, I'm going to get out just to kind of expand it out a little bit and up here. Let's have a look at it on the layers. The original, it just expanded a bit more. Might even feather it haven't feathered it. I haven't heard anything a long time. Ah There we go quick. Okay, got rid of that kind of really strong edge there. Alright, that is not a particularly good photo. I shot it right now. This is the desk I'm sitting at just as an example. I want to tidy up these, these cables Now I made this desk and while it looks kind of cool. I like it. I made it, I made a big ridge exactly where the mouse goes, which doesn't make it useless. But it makes it a terrible desk for anybody using a computer. Anyway, auto align. You might be thinking in your head. I can think of other good ways in my situation to be using it. I use this for exposure. It could be focused links, it could just be, you've got images, you just need to line up some people do it where you've got like a staff picture and you say, Okay, everybody say Jesus and most of them look except for Sandra. Sandra's not looking at the camera, but in the next photograph Sandra's looking. But Dave isn't I don't know who these people are. So what you can do is you can line them up and then mask out Sandra's face on one of them and have it. So both Dave and Sandra are looking at the same time. Alright, my friends, that is going to be it. Let's get into the next video
