Damjan Jovanovic commented on SANSELAN-55:
------------------------------------------
I'm not sure. Here's what exiftool gives for that image:

and Sanselan:

Exif metadata:

-----------------------------------------------
So exiftool's "IFD0" and Sanselan's "Root" seem to agree - Sanselan doesn't
recognise some of the fields, but they are in the same order and have the same
values. I'll have to investigate further.
