# Description:  Sigma/Foveon EXIF maker notes tags

# Revisions:    04/06/2004 - P. Harvey Created
#               02/20/2007 - PH added SD14 tags
#               24/06/2010 - PH decode some SD15 tags

        These tags are written by Sigma/Foveon cameras.  In the early days Sigma was
        a class leader by releasing their maker note specification to the public,
        but since then they have deviated from this standard and newer camera models
        are less than consistent about their metadata formats.
