Video: Reducing exaggerated distortion

Here I want to build upon what we already know about the Lens Correction Filter and take a look at now how we can use the automatic and custom adjustments together and also how we can add some of our own adjustments after the fact inside of Photoshop. We'll be working with this photograph here which I captured of one of my neighbors' house. It was all decked out for the holidays and there is some fisheye distortion because I was using a fisheye lens. Let's see if we can remove some of that or perhaps take some of that out. First, let's copy our Background layer.

Reducing exaggerated distortion

Here I want to build upon what we already know about the Lens Correction Filter and take a look at now how we can use the automatic and custom adjustments together and also how we can add some of our own adjustments after the fact inside of Photoshop. We'll be working with this photograph here which I captured of one of my neighbors' house. It was all decked out for the holidays and there is some fisheye distortion because I was using a fisheye lens. Let's see if we can remove some of that or perhaps take some of that out. First, let's copy our Background layer.

We can do this by clicking and dragging to the New layer icon or you can press Command+J on a Mac or Ctrl+J on Windows. Let's name that layer corrections. Next, we'll go to the Filter pulldown menu and here we'll choose Lens Correction. We're going to start off in the Auto Correction tab. If the file that you have has data embedded in its metadata about how it was captured, this can help out Photoshop. Here Photoshop is picking up some options, some profiles. I'll click on the correct profile for my camera and lens combination.

Already, the default or automatic correction is pretty good. Here's before, and then here's after. Yet a lot of times you'll need to customize this or push this a little bit further with the custom settings. That's all we covered those in the previous movie. So here let's go to the Custom tab. In the Custom tab, we can remove more of the distortion by clicking and dragging, yet when it comes to a lot of distortion, if you move these sliders too far, as you've seen, you can start to reintroduce that. So you need to try to find just the right spot where you're removing the distortion but not adding more into the image.

Next, we can control some other distortion by using our Transform controls. If you click-and-drag this to the left, what it will do is it will kind of help the photograph almost lean forward. Look how we can have that lean back or forward by moving these controls. And here I need to make this lean a little bit more forward. Now if we captured this off-axis, we can also control that by clicking and dragging to the left or the right. And sometimes if you are a little off-axis, this can help just kind of level things out a bit. Well after having made those adjustments, you may need to go back and change your Distortion amount as well.

Okay, well here I think we've made some pretty dramatic adjustments with this image. Only thing I want to do is perhaps change my angle here just a little bit and then click OK. Once we click OK, it will apply those adjustments, and we can see here's our before, now here's our after. We have removed so much. What else could we do here? Well after having used the Lens Correction Filter really to the tilt, using those automatic and custom controls, I want to then copy this layer. To do that, press Command+J on a Man, Ctrl+J on Windows.

I'm going to name this new layer free transform. One of the ways that you can make distortion corrections is by accessing Free Transform. You can do that by going to Edit and then choosing Free Transform. If you just use this kind of in-the- generic way, you can move these corner points and change the size of your image. Yet, in order to work with different types of distortion, you can click on this little icon here. This little icon which is often overlooked allows us to access this Warp mode.

By accessing this, we can then click-and-drag these different points. And as I do that, you can see that I'm really changing the overall shape of this area of the image, and primarily, it's like I'm working on that one quadrant. Well these are all connected, so of course as I move one, I may need to move another as well. And as we work with these, we can either click on the lines in order to change this, or we can click on these corner points. Well what might we want to do here say with this photograph is just pull out some of these little points a little bit subtly here in order to try to bring down the edge of the photograph.

And in doing that, I'm just looking in trying to possibly remove a little bit of the distortion over here. Now this won't be perfect but it's definitely something that you want to know how to do because there are situations where this can really help out. I'm just opening up these side points and then I'll go ahead and click-and-drag up to make this a little bit taller as well. Now I need to be careful, because I feel like my bottom right corner is just a little bit too far there; it's not quite good enough for me, so I'm just going to try to tweak those adjustments. This is really subtle, right, because we're making these big adjustments, or I should say, we need to be really subtle, because we want to be careful that we're not swinging things too far.

Well, here we can then press Enter or Return to apply those warp adjustments. Well what did those do? Well if we look at our before and after, here's before and then now here's after. It basically just kind of leveled a few things out and kind of pulled a few elements out. If we look at our overall before and after, we can see that by using these different techniques, well it helped us to correct this amazing or intense amount of distortion. Now the image isn't perfect yet; it's getting a lot closer, and I used this file to illustrate how powerful these different techniques are, so that you can then see how you can use these techniques in order to correct the distortion in your photographs whether you have this much distortion or less.
