Lens Correction in Photoshop CS5 is bound to get a lot of attention, especially because of this new Auto Correct feature. As we saw in the last movie, one of the things that we have to do, quite often, is to use Auto Correct and then modify the correction a little bit further with those custom controls. And because those two work so well together, I thought it would be helpful just to throw in another little bonus movie where talk about some of those custom controls. Therefore, you can get the most out of the actual automatic correction. Here, what I'm going to do is navigate my Filter pulldown menu, and then select Lens Correction.
Now once this opens up this dialog, I am going to go straight to the straight to the Custom controls here, and here in this sign we can see that there's quite a bit of distortion. In order to correct this distortion perfectly, it's going to be near impossible because of the perspective of the camera was really low, wide-angle lens, yet nonetheless, we can start to see how we can use these controls. Now one of the things that we've already begun to talk about is how we can remove distortion, and in this case, all I want to do is to do a little bit of a removal or pincushion the image. In that sense, it's kind of bringing the image in just a bit there and we can see how that's working.
Now again, this isn't going to be perfect, but it's starting to change some of those lines. Next, I'm going to go ahead and change my Vertical Perspective, and as I do that, I run into an issue. One of the issues that I see is that it's cropping off the top of the image. What you can do is modify this scale Amount. It's really interesting when you do this because it can help you begin to deconstruct what's happening here with the photograph. Now in this image, you can see there's transparency around the edges where the image was distorted. One of the reasons why I wanted to include this movie is because in order to change that, you'd actually have to go back to your Auto Correction tab, and here what I'm going to do is select a different option.
We can choose Black or White on the background or Edge Extension. Now Edge Extension will work to a certain extent. We can see that it did an all right job here on the sides on the top, but on the bottom, things really start to fall apart. That being said, sometimes it's worthwhile to have that on and sometimes you can crop your images just a little bit bigger having that Edge Extension option turned on. All right. Let's go back to your Custom controls here, and again, all that we want to do is just modify this a bit. And I'm going to go back and forth, changing this as needed, make a little bit of change with regards to vertical, and I go back to my Distortions here up top.
And I can also control the Vignetting. One of the things that happens a lot of times with wide-angle shots is that those edges become a bit dark. In this case, I'm just brightening those up in order to bring in a little bit more even light on this area of the image. I can also make other adjustments as well. We can modify the Angle or the Horizontal Perspective, but for the most part, I think we're getting to a good range. Let's press the P key. There's our before. Press the P key again. There is our after. The last thing that we'd want to do here would be to simply click OK to exit out of this, and then to render that particular filter effect.
Now at this juncture, we can even take this further if we want to. For example, you can press Command+T on the Mac, Ctrl+T on the PC and then what you can do is hold down the Command or Ctrl key. And you can click and drag your corner points. And you can do this in order to change this particular perspective. And here you can see that I'm just pulling these two points out a little bit, which, in turn, is bringing the top of the image a little bit more forward. There's quite a bit of work that you can do on the image, either by moving your corner points, or for that matter, by opening up the Warp tool.
With the Warp tool, we can click on the image. And here you can see how I'm really bending the photograph in some unique and distinct ways, kind of controlling a little bit of the overall shift here and looking to try to correct this image a little bit more, just removing a touch of that bend in this area of the photograph. I can bring this area down too. So, it's simply clicking and dragging on our image in order to make further corrections. Now, I am aware that we are kind of digging deep into this whole topic. Yet, the whole point here is that this new feature of Lens Correction isn't a stand-alone feature.
It's not save the day feature. Rather, I see it kind of as a great starting point. Now on some images it just works fine, and that's all you'll need to do. Yet other images, what you need to do is to combine that with what we already know about how we can correct our photographs. Well here I'll go ahead and press Enter or Return to apply that particular correction, and now the image, again, is looking much stronger. The last step would be, of course, to crop this image. There are a lot of different ways to crop photographs. One technique that you can use, though, to create a little bit more of a freeform crop is to select your Marquee tool, click and drag across the image and then go ahead and choose Image and select Crop.
That will then crop away everything but that selected area, and now here at this juncture, we have brought this image to new place, and it's looking much better. Good work.
