In this movie, we will continue the conversation which was started in the previous movie. And here I want to dig a bit deeper into how we can work with our lens correction controls in order to crop and straighten our photographs. And I also want to highlight an important feature which allows us to constrain the crop to the image area. I'll be working with this image here, it's called eric.dng, and this is a portrait of my friend Eric, who's an artist in his studio, and you can see that this image isn't level. You can tell so by the lines and whatnot in the background.
There's a slight tilt to the photograph. Or here lets began to correct that in the Lens Corrections panel, so click on that tab and began by navigating to the Profile tab. And then choose the option to enable the lens profile corrections. This will ensure that our results are that much better later. Next we'll click on the Manual tab and here in the Manual tab we have four different options when it comes to our upright controls. The first option is automatic. This is the option which will typically work best on most of your photographs.
This will correct perspective issues. Also will level the image out horizontally and vertically. We could also try these other options. This is a good option. It will level out those lines horizontally, or we can level our vertical lines. Or we can apply a full correction by clicking on this button here. I find that full works best when you have a lot of distortion in the image, and upright works best again for the majority of your photographs. Alright, well now that we've applied this upright correction. What I want to do is talk about another feature, which we have here which is about how we can constrain our crop to the image area.
In order to talk about that, I need to make kind of a silly adjustment to this photograph. You know, one of the things that we can do with our sliders here is we can make some dramatic perspective corrections to our photographs. For example, we can rotate the image here with this rotate slider and as I rotate this you can see that now everything obviously isn't level. But perhaps let's say that I want to create a different image, I want to tilt the image a little bit to try to create a different type of a mood here with this photograph. Well in doing that, all of a sudden I can see into the background here where I have transparency.
If I go to crop my image by selecting the crop tool and just click and drag over the photograph, I can crop the photograph but notice that my crop area is going to be inside of this transparent area. Or if you want to make sure that your crop always snaps just to the area were we have pixels. What we can do is we can click and hold down on the crop tool and then choose this option which is constrain to image. Here now, when I crop the image, however I crop it it will only allow me to drag this right to the edge of the frame there.
As I rotate the image that will then change how I can crop. Because, again, it's just going to maintain that, that crop area will be inside of that actual image area. The reason why I wanted to highlight that here is often as you start to work with these lens correction controls. You may run into that issue and may decide that you want to crop the image, and often, when you're doing so, it's a good idea to turn on this option, constrain to image. Just to ensure that as you crop the image it will be inside of that particular area.
Now with this photograph I actually don't want to tilt it so here I'll go back to my Crop tool and I'll choose Clear Crop and then I'm going to bring my rotation back to the default setting. I think this environmental portrait looks better simply with some automatic adjustments applied here with upright. It corrected some of those perspective issues and made this image look more natural.
