Converging verticals often occur when the camera tilts up to include the top of a building. The vertical lines will collapse towards the centre. This is exacerbated by using a wide-angle lens, which exaggerates perspective.
A similar issue can occur when the camera is tilted downwards from a high vantage point, as in this image of Florence. The downwards tilt has caused the vertical lines in the cathedral to taper inwards towards the bottom, and as such the building initially looks distorted and top heavy.
Affinity Photo offers several tools for correcting verticals and adjusting perspective. First there's Perspective, which lets you move the frame into position, and there are the Lens tools. However, perspective corrections can leave the scene looking squashed or stretched. What's more, you often need to pull in the top or bottom of the frame, resulting in empty corners. A crop can fix this, but what if the original framing doesn't leave room for cropping? Here's how to tweak perspective and correct other problems... Find out more at affinity.serif.com/photo
