Video: Straightening perspective with Adaptive Wide Angle

The Adaptive Wide Angle Filter is intended to be used to fix the kind of distortions that happen with wide angle lenses, especially the bowing of horizons. But you can also use it to create symmetrical compositions like this Pro Images that began like this. Showing the typical kind of Keystone effect that you get, when you point your camera upwards. And here I'm using it with two other Photoshop tools. One of them a filter, that's the lens correction filter, which is really doing half of the work here. And adaptive wide angel is just finishing off, and also the content aware fill. If we just break that down, we can see that applying lens correction straightens out to a large degree those distorted edges.

Straightening perspective with Adaptive Wide Angle

The Adaptive Wide Angle Filter is intended to be used to fix the kind of distortions that happen with wide angle lenses, especially the bowing of horizons. But you can also use it to create symmetrical compositions like this Pro Images that began like this. Showing the typical kind of Keystone effect that you get, when you point your camera upwards. And here I'm using it with two other Photoshop tools. One of them a filter, that's the lens correction filter, which is really doing half of the work here. And adaptive wide angel is just finishing off, and also the content aware fill. If we just break that down, we can see that applying lens correction straightens out to a large degree those distorted edges.

And then adaptive wide angle just takes it that bit further. Inevitably, that is going to leave some gaps around the edges and that's where the Content-Aware Fill comes in. So, I'm going to switch to the beginning state, convert to a smart object, and then come to lens correction first of all. And in terms of the auto correction, let's turn it on. It's not going to make a whole lot of difference here, but I don't think it's going to do any harm either. I have a grid turned on, and I'm going to use that grid to just visually align the edges that I want to be completely straight or completely horizontal. Of course, I'm also losing some of the edges of the image so I can compensate for that by changing the image scale, so I bring the image back and I'm also going to use the straighten tool.

There is a line that runs down the middle and I'm going to straighten to that line or attempt to straighten to that line. I'm dragging the straighten tool across that line, and then you can see, as evidenced here in my angle, it's slightly shifted according to that line. So, there's my starting point, I'll now click OK to that. And then come up to adaptive wide angle. And there are two tools here that I'm going to use. The first is the polygon constrain tool, and this is going to do the macro work.

And I'm going to, in this case, just draw myself a polygon around the area I want straightened. And I'm holding down my Shift key to constrain these lines to be perfectly horizontal or perfectly vertical. So that there is a start and now, I'm going to switch to my Constraint tool, and you can see on the top here, this Window that was outside of the polygon has not been straightened, though, is slightly bowed. I'm gonna draw myself a line running along the top of all those window ledges. And that will straighten that line, and I'll add a few more of these in. There is a limit to how far you can go with this, and if you go beyond that limit, you are gonna do some damage to that image. But, I'm gonna carry on while I'm still ahead, I think I'm still ahead. And I've also added some vertical lines as well. Okay, so now I am going to have to crop this.

I'll tap C to go to my crop tool, and I'll bring in my cropping rectangle. To about there and let's see how content aware fill will do now trying to fill in these empty areas. It's a big task for content aware fill, but I am often amazed at how much it can do. I will duplicate that layer, and then I'm going to restorize it.

Tap W to choose my Wand, unchecked contiguous and then click in an area of transparency. I'll now come to the select menu and expand that selection and I'm going to expand it by 40 pixels and then press Shift, and my Backspace + Delete key, and use content aware to fill that area. Not such a great job here on the left, but a pretty good job over here on the right. And I'm going to use the path of least resistance to fix that problem, and that is I'm going to crop out any obviously cloned areas.

But there we see an interesting and promising use of adaptive wide angle, whenever you want to create something that looks symmetrical and grid-like.
