I don't mean hugin should modify the images - only rotate what it has
in memory. As you can see from my outporings, no matter what setting
or raw processor I tried, the Orientation tag is always 'horizontal'.

Looks like the only place the information is kept is in the unofficial
Canon tag.

Thanks for pointing that out. I didn't go that deep in my
investigation. So I must consider myself lucky that at least my camera
produces a tag which the other tools don't destroy :-)

I suppose I'll have to finally make the effort and write a
comprehensive script which deals with my specific scenario - not only
the troubles with the orientation, but also the missing lens
information (I use a manual fisheye lens) and the geotagging (no built-
in GPS) - and I might have cpfind make keyfiles there and then...
