Hugin 2021.0.0.52df0f76c700 on Windows 11
If this is documented somewhere, please point me at it. I've not seen anything, though.
I have a horizontal series of five portrait images but the pano always curves upward to the right.
- Tripod was level
- Camera was level
- Plenty of overlap
- EXIF is in the TIFFs
- Sigma 17-70 DC lens at 36mm
- Camera is a Canon T8i / 850D, 1.6 crop sensor
I've done many panos in the past from less-level handheld images through the same lens using Hugin (both this camera and another), so that's not the issue.
For reference, here are thumbnails of the images, left to right, nice and level:
There are about 30-50 control points per image pair. Ideally I'd like to have more, but I've been successful with fewer and these look OK to me. None are in the sky, etc.
But the pano always looks like this:
If I click Straighten, I get this:
I've enabled rotation detection, removal of sky control points, etc., but no change. However if I display CPs on the preview there are some in the sky, apparently but they're not visible on the Control Points tab:
I'm not super confident in what I'm reading, but this looks suspicious to me:
Why the seemingly excessive roll values?
If I try to optimize everything I get this:
...so I click No.
Am I doing something wrong? I'm no Hugin / PT expert by a very long shot, but I've used it for more than a decade and have rarely if ever run into this kind of issue.
