        # From the Microsoft documentation:
        #
        #     Any time the "Maker Note" is relocated by Windows, the Exif MakerNote
        #     tag (37500) is updated automatically to reference the new location. In
        #     addition, Windows records the offset (or difference) between the old and
        #     new locations in the Exif OffsetSchema tag (59933). If the "Maker Note"
        #     contains relative references, the developer can add the value in
        #     OffsetSchema to the original references to find the correct information.
        #
        # My recommendation is for other developers to ignore this tag because the
        # information it contains is unreliable. It will be wrong if the image has
        # been subsequently edited by another application that doesn't recognize the
        # new Microsoft tag.
        #
        # The new tag unfortunately only gives the difference between the new maker
        # note offset and the original offset. Instead, it should have been designed
        # to store the original offset. The new offset may change if the image is
        # edited, which will invalidate the tag as currently written. If instead the
        # original offset had been stored, the new difference could be easily
        # calculated because the new maker note offset is known.
        #
        # I exchanged emails with a Microsoft technical representative, pointing out
        # this problem shortly after they released the update (Feb 2007), but so far
        # they have taken no steps to address this.
