Not sure if that’s a bug or a feature.
Images of the same camera, lens and focal length are sorted into two different groups depending on whether they have been shot in landscape or portrait. Since the distortion does not change at all, would it not make more sense to put them all in only one group? If there are enough images of both, it should not matter much but in rare cases it could cause some problems…
BTW, they are developed JPGs from RAW.
PROMO and still on 1.0.2.2935
Not a bug.
All photogrammetry tool for avoid wrong rotation tags after preprocessing or from camera decided treat different rotation as different lens group.
So first step after copying images from SD card will be better remove rotation tag from images.with Exiftool.
“c:\Program Files (x86)\Exif Tool\exiftool.exe” -Orientation=1 -n *
(do not forget delete *_original files when process finished successfully)
Ungroup images only in final align refinement if needed.
Ah, ok. Thanks for the explanation and the solution!
