Thank you. That answered part of my question. I'm still wondering how it determines the orientation of the panorama though.
Let's say I take photos with a panoramic head at random y,p,r orientations (so there can even be photos taken in portrait format, others in landscape and all the in-between angles). If I stitch them in Hugin and then click on "Straighten", will it determine a "dominant" orientation so that the equator of the panosphere is closest to as many photo centers as possible or will it do something else ? I may do some tests to understand it better. On Wednesday, May 8th, 2024 at 4:27 AM, David W.
