Hello Pierre,
In case of the file-creation-date of an image in filesystem and its "exif:date/time original" is different,
XnViewMP always displays exif:orientation always with value: 1=top-left
while Exiftool displays the correct value.
In order to reproduce,
- take a *.jpg image with creation date different to its exif values
- do a rotation with only changing the exif:orientation tag.
Please do a correction within next release.
Thanks in advance and
Best regards
Herb
