Eliminate the keystone effect

- [Voiceover] Let's take a look at correcting the keystone effect that happens sometimes, especially when we shoot buildings. So I've added some new shots to our library here. Yeah, something new for us to look at. In fact, before I show you keystone correction, and again, we're here in the Composition tab, let me show you how I added these images to the library. So I did an import and I created a new group called Places. And I created a project for these images.

And then I created an album called All Photos, and I went to the recent import here. And then I just grabbed these images and pulled them into All Photos. And here we are now. So now we have Portraits, Things, and Places as our main groups. And then, of course, inside of them we have projects and albums. So our library is shaping up nicely as we move through this course. Okay, let's go back to Composition. Here we are. And let's fix some keystoning effects.

I shot these images with an iPhone 6s, really good camera on the iPhone 6s. But I was at ground level, and of course I got this effect that most of us are familiar with. And it's very easy to correct. Down here we have three semi-automatic corrections: vertical, horizontal, and then this is basically both directions. Now unlike some of the other tools in Capture One Pro, the A up here, the Auto, does not work for regular cameras in the keystone correction.

It is a specialized tool. I believe it works for some Phase One backs, things like that. But it won't work for you if you're shooting with an iPhone or an Olympus or Canon, whatever. So for this particular adjustment, we ignore this. All the other things up here, such as Copy, Reset, and then of course our little Save User Preset, all that, that's all the same. The A's the only thing that's different. So for our automatic corrections or for our semi-automatic corrections, we're going to go down here.

Let's go to Vertical. So you notice that that's highlighted now and we move from here, the select tool over to the vertical correct. And we have these little handles here I can grab. And all I'm going to do is just line them up with the vertical lines that I want to correct. See, just like this, I'm lining them up with the pillars there. And as I do that, I get the Apply button right here, and all I have to do is click on it.

And we have applied our correction. Now again, we're seeing these areas here that you might not want to see. And just like with the cropping tool, all I have to do is go back to Select and there's our correction. Isn't that nice? That was just really, really slick. So we also have horizontal corrections. Although, this is another vertical shot here. Let's just try where we have all four. Let's see what I can do. I'm going to do something like this right there.

And we'll just do something like this right here. Let's apply it and see what we think. Go to the Select tool. Not bad at all. Now, you can play with this. We have these sliders here. So you can continue to play if you don't want to use just the automatic tools. And we have the Reset so we can go back. And you have the Horizontal also. And then, you have an Amount slider.

And this is really how much of the effect do you want to what you just did. Heh, ha. It's one of those sort of things. So if I did this here, the amount slider is like, okay, a little bit more, but you sort of got the angle you want. Now, how much more of the effect do you want? Something like that. And then, Aspect, that readjusts the images to compensate for the stretching that happens. See, now here I'm using aspect to actually create stretching, but if a little bit of stretching happened and I wanted to downplay that, then I could use the Aspect to help kind of pull that back into line.

I'm going to hold down the Option key and click on the Reset. So there's where we were. Here's where we are. Nice little fix, don't you think? So play with this. Bring in some images to your own library that have this perspective problem, the keystoning. I would use these two most of the time, although all four is nice, either one. But the vertical, horizontal, and then the all four points, they all work terrific. I think it's a little bit easier starting with these than to just start moving these sliders because these actually give you the guides to help you out there.

And then, you can always reset if you don't like what you did by hitting the Reset here. And you can hold down the Option and press Reset if you want to compare to your original image to make sure that you're actually moving forward. But it's a pretty powerful tool, and it's great for shooting architecture, especially when you're on ground level looking up.
