Correcting distortion with the Adaptive Wide Angle correction


Photoshop CS6 for Photographers

Video: Correcting distortion with the Adaptive Wide Angle correction

Now, we are going to take a look at how we can correct the perspective in our panoramic photograph, and in order to do that, what we are going to do is we are going to merge all of the underlying layers to the topmost layer. To do this, we need to use a shortcut. Now, I have to warn you, this shortcut, well, it's a mouthful. There are a lot of keys, yet it's a really valuable shortcut, because it allows you to take everything you've done so far in regards to your layers, and just to flatten or to merge all of that to the topmost layer. Well, here it is! Here's the shortcut, on a Mac, you press Shift+Option+Command, then the N key, then the E key.

Correcting distortion with the Adaptive Wide Angle correction

Now, we are going to take a look at how we can correct the perspective in our panoramic photograph, and in order to do that, what we are going to do is we are going to merge all of the underlying layers to the topmost layer. To do this, we need to use a shortcut. Now, I have to warn you, this shortcut, well, it's a mouthful. There are a lot of keys, yet it's a really valuable shortcut, because it allows you to take everything you've done so far in regards to your layers, and just to flatten or to merge all of that to the topmost layer. Well, here it is! Here's the shortcut, on a Mac, you press Shift+Option+Command, then the N key, then the E key.

That allows you to create that new layer and then merge everything to the new layer. On Windows, that's Shift+Alt+Ctrl+E.By doing that, you can see we merged all of these underlying layers up here to this topmost layer. We need to do that or we would need to flatten down in order to be able to correct the perspective because we need everything on one layer. I chose to merge to top so that we can have those original layers still in the document in case we make a mistake, and also to be able to show you the before and after.

We are here at this top layer. Let's go ahead and just name this pano. Next, let's press the F key to go to Full Screen mode so we can really focus in on the task at hand. We're going to use a really powerful filter. If you go to your Filter pulldown menu, you can select it here, it's called Adaptive Wide Angle. Once you choose that, it will open up a new dialog. And as you work in this dialog, one of the things you are going to have to keep in mind is that you're typically going to be zoomed way out. Yet, you kind of need to get familiar with that or get comfortable with that, and you need to start to identify some problems that you're seeing in regards to perspective.

Well, what you can do is you can start to correct those by using these tools. Here, I will go ahead and hover over my image and I am going to click-and-drag along this roofline here. As I do that, you notice that there's a little bit of a curve. It then followed that curve and then corrected it. It then added this icon or these icons above this area that I just modified. Well, here what you can do is you can hover over this, and you can click and rotate. What I'm interested in doing is making this a little bit more level, so here I'll go ahead and do that and now I've leveled out this part of the image.

We can also click-and-drag to extend or to decrease the size of this and you can see how it's affecting more or less of the image as I make this bigger or smaller. Now, with panoramics, depending upon how they're shot, you're going to need to make a lot of little adjustments like these, and as you make these adjustments, well one adjustment will affect another. Let me show you what I mean. Here, I notice that this area is really curved, these steps and this wall here. Let me zoom in on that a little bit. We can do so by pressing Command+Plus on a Mac or Ctrl+Plus on Windows.

Next, I'll go ahead and click here and then drag along this. Notice how my line is bending, it's figuring out that there is distortion there. Now, when I click and let go of that, it's going to try to correct that distortion. And in this case, it did a really good job. Again, we can move these points in order to change how this is affecting the overall area of the image, and also how much of this image has been corrected. Well, so far, we're making some pretty good corrections. Let's look at our before and after. Here we have before and now here is after.

Well, already with this, I could almost use this just to crop out this area of the image to create a panel. But I want a little bit more of this courtyard. So what else can we do here? Well, we can work on the sides of this image as well. For example, here I will go ahead and click around this area, and then drag along this roofline, and I will just move this over so I can get all of this. And perhaps, I should zoom out as well here, but let me just try moving that over. That straightened up that roofline, but the angle is all off. So again, if we hover over this Circle icon here, you can go ahead and click-and-drag down.

I'm watching the degrees, and I'm trying to make this close to level; 0.4 is pretty close, and you can see how it's corrected that part of the image. Well, we also need to correct this path down here, so again, I will set another point. When I set that point, I accidentally let go of the cursor button, so this line was really short. Well, I can just click-and-drag to extend that out. Also, if you create a line that you want to delete, well just click on it, and then press the Delete key, so again, you can see how I can target these different lines which we've created.

Well again, our panoramic image is making some great progress. Let's work on this side. So press the Spacebar key and click-and-drag to the right. Next, here I'll go ahead and click-and-drag over this area. I want to straighten that up and then also rotate this down a little bit; looking to try to create a little bit more of a level line there, and I want to work on this roof over here in this whole area of the image. This is going to take I think a couple of adjustments. Notice that the palm trees, they are leaning a little bit to the left.

So first, let's try to just click-and-drag over this area, and then what I want to do is rotate this down. I want to try to bring this down, so that again, it's closer to be in level. Now, by doing that, it also helped out with my palm trees. I am just going to modify this a little bit, so I can see that those palm trees are straight there and also so that I have nice detail in regards to the side of the image. Well, as I make all of these adjustments, we can see that the image or the pano here, well it's looking a lot better. If ever we want to go back and change things or change the way we've leveled this out, just go back to those points and you can modify them.

Here on the left, I'm realizing that it was kind of tipped down too far. I think I got a little overambitious with that adjustment, and I want to bring that up. Same thing with this line down here; I am just going to look to bring that up a little bit more here. And as I'm doing that, I think that's helping me to create some better results. We can also create lines which are vertical. Here, I can go along this palm tree, and if I want to tilt this over, I can go ahead, and click-and-drag that, and you can see how it's kind of leaning that to the left or if I wanted to lean to the right, I can do that as well.

If ever you have a point that you want to get rid of as I mentioned, click on it, and then press Delete or Backspace. Here, we have made some immense improvements with this photograph. I mean, this is pretty unbelievable. If ever we want to make more, say we want to work on the tower, well just click-and-drag to create a line there, and you can change that as well, perhaps, I want to move that over to the right a little bit, or have this line of the building, touch or move over a bit to the other side. So as we're making all these fine-tune adjustments, we are really trying to analyze the lines and the way that this image looks, and how we can try to make this look its best.

There is a lot of detail work, and again it's kind of the zoomed out perspective. But what we're ideally doing here is having this vision for how we want this panoramic photograph to look. Well, I know that there were a lot of little teeny steps that we took there, but basically it was using this one tool, and modifying those lines in order to make corrections. After you've done all of that, the next thing you want to do is just click OK in order to apply those corrections. So now here we have the corrected image up on this topmost layer, the next step of course is going to be to crop the image, and then we need to fill in a few areas, and we also will want to make some final color and tone adjustments.

So let's take a look at how we can finish this project off and let's do that in the next movie.
