If you've ever been out and about and taken a photo of a tall building with a wide angle lens, you've probably noticed a weird phenomenon in which buildings appear to be falling away from you or into the center of the frame. This helpful video will show you how to correct perspective distortion using only Lightroom.
Very often, people walk around a city, taking architectural shots by pointing the lens at an angle above the horizon to fit the buildings in the frame. This results in vertical perspective distortion, which makes it look as if the buildings are not upright and are falling away from the camera. If you want to correct those issues in camera without changing your framing, you'll need a tilt-shift lens, but if you're just looking to correct just a photo or two at a time, Lightroom has some excellent options, including the Guided Upright tool, which Nathaniel Dodson shows how to use in this tutorial. While you'll lose a lot of the image to having to re-crop it and a dedicated tilt-shift lens will generally give sharper results, it's a very good and mostly acceptable solution, particularly for those of us who don't specialize in architecture. Give it a watch!
