This is one of those things that you might only ever come across once in the blue moon, but when you do, it’s useful to know how to fix it. If you’re shooting with a wide-angle lens, something like a 24mm or wider, and you have people at the edge of the frame, they can be distorted. This is especially true when shooting in portrait orientation and looking up. Like I said, this is a very specific situation, and it’s only by chance that I knew how to fix this.

DxO Labs has announced the release of DxO ViewPoint 5, an updated version of their specialised photo editing software. This tool is designed for photographers who need precise control over image geometry, perspective correction, and the effects of wide-angle lenses.
