After having looked at how we can work with the Automatic Profile Lens Corrections, let's also take a look at how we can work with the manual controls. So click on the Manual tab and here you can see you have a set of controls. These controls allow us to modify different types of Distortion whether it's barrel or keystoning distortion, we can rotate and scale the image. We can also add or remove a vignette. Let's start off with the controls at the top. In regards to these here what we can do is we can change the overall barrel distortion. You can see as I move this in and out, I can control how the image will be distorted.
Now as we try to correct the image, you may see that it's going to bring in part of the image that's been modified, so that there aren't any pixels there. Well if you see that, you can always crop that out or you can use the Scaling Slider in order to scale in so that that area isn't visible inside of the document frame. Next with this slider we can control this vertical issue here and here you can see that what's happening is rather than having the image look like it's leaning back, we can click and drag to left so that everything is a little bit more straight up and down.
Next we have Horizontal, here we can control our axis; if we're a little bit off axis, we can then change that. And in this case this helps a little bit because you can see how I was a bit off axis on that side, so by bringing that around, it just levels things out a little bit. We can also Rotate in order to change the perspective that we're seeing here, and then finally as I mentioned before, we have the Scale option. Now when making these adjustments with the manual controls, we have a lot of power. With the Profile it kind of did it all for us. Here, we're dialing it in slider by slider.
If we click on the Preview button you can see here's our overall before and after. And really, we're not able to accomplish such dramatic distortion removal without using both of these tabs together. Yet with other photographs you may find that it will work just fine working with one of these two tabs. May be the Profile Correction will do everything that you need it to do and you'll be done. Yet in other situations, like with this photograph, it may be helpful to work with both tabs and both sets of controls. And then again before we wrap up this movie, I just want to highlight that we also have Lens Vignetting Controls here.
Now we won't really be able to see these because this image is already so dark. You can kind of see it slightly darkening or brightening the edges. Yet I do want to show you how you can work with these controls with another photograph. So let's go ahead and continue talk about how we can correct and enhance our photographs using the Lens Corrections panel and let's do that in the next few movies.
