Hugin knew better than I did!
- I have been struggling with merging two 4 x 5 images taken with a
panoramic head, one turned 15 degrees to the left, and the other turned
15 degrees to the right. I also used a vertical rise in my view camera.
The problem was that whatever I tried, hugin insisted on showing the
building with the bottom not parallel to the top. I finally went back
and checked carefully. Hugin was actually showing me just what was
I was assuming the ground was perfectly level. It certainly looked that
way, and I assumed it was a safe assumption in this area just north of
Chicago, close to Lake Michigan. But checking with a level and looking
carefully at the building showed me that there was in fact a significant
rise from right to left at ground level. The height to the roof, which
presumably is level, may be as much as 2 feet shorter on the left than
on the right.
