So I'll have to wait for the release...

As far as I can see, there is an exif info but no orientation tag in the exif 
properties.

That's what I tried to do, but does not work.
So this only works, when there is already an orientation tag? Is there any way

Is exif that complicated, that there is no program, that can create exif tags, 
rather than just change them?
