View and Modify 360 Photos in Affinity Photo
If you have some 360 photos and would like to use parts of the images, you can do that in Affinity Photo. You can zoom in and out and "fly around" to find the perfect place to export as a picture. In addition, you can use Affinity's powerful touch-up features to clean up your 360-degree photo.
