Reference original image, taken with an 8 mm lens on a 1.6x crop body (Sigma 8-16 on Canon 7DmkII) [1]
I should note that initially everything is fine -- the mapped photos look reasonable. However, at some point during the optimization process, and I have not managed to track down when, the below behavior manifests itself if I'm using a very wide angle lens. I tried to reproduce it from scratch, but wasn't successful -- I didn't find the exact point at which things went off the rails. It appears that Hugin is cutting off the corners of the frame [2]. I'm presuming that that's to avoid severe distortion, which is nevertheless still visible near said corners. When Nona remaps the images, that corner distortion is still present. Enblend seems to be able to avoid using those areas [3], but multiblend (which is otherwise preferable for the most part) doesn't [4]. I also note -- and I've mentioned this previously, in 2014 [5] -- that the OpenGL preview shows some really weird errors [6], which the slow preview doesn't [2]. However, in 2014 the corners were not cut off [7].
