Hi Simon,

Storing the orientation of the camera relative to the image data stored doesn't make much sense and just happens to kind of work for exif aware applications, because the camera abuses the ORIENTATION tag.
The ORIENTATION tag provides enough flexibility to cope with situations other than just "Portrait" or "Landscape"; the typical camera's use of the ORIENTATION tag isn't so much an abuse of it, as a special case.
FWIW though, my old HP PhotoSmart 618 does indeed rotate the image data before writing to the card, and ignores the ORIENTATION tag - so it has been done!
(It also has a Coldfire processor, and uses Digita as its OS...)
All the best, -- Alastair M. Robinson
