When you’re photographing interiors or tall buildings, perspective distortion is often inevitable. There’s ways around it with tilt shift lenses or large format film cameras, but for most of us that’s not an option. These days, Lightroom, Adobe Camera Raw, Photoshop and other tools provide a number of fancy automated ways to help correct for this. Sometimes, though, it doesn’t quite hit the mark, and we need to step in and do it manually.
This particular type of perspective distortion is commonly known as “converging verticals”. It’s caused by things getting smaller as they get further away from the camera. It’s essentially the same thing you see when looking down a straight set of train tracks that seem to eventually arrive at a point. Only, this happens vertically when shooting up or down on objects oriented vertically. Fixing it manually is fairly simple and straightforward. This video from the folks at Sleeklens shows us how.
