# Notes:        There really isn't much public information about Kodak formats.
#               The only source I could find was Image::MetaData::JPEG, which
#               didn't provide information about decoding the tag values.  So
#               this module represents a lot of work downloading sample images
#               (about 100MB worth!), and testing with my daughter's CX4200.

        Kodak models such as the ZD710, P712, P850, P880, V1233, V1253, V1275,
        V1285, Z612, Z712, Z812, Z885 use standard TIFF IFD format for the maker
        notes.  In keeping with Kodak's strategy of inconsistent makernotes, models
        such as the M380, M1033, M1093, V1073, V1273, Z1012, Z1085 and Z8612
        also use these tags, but these makernotes begin with a TIFF header instead
        of an IFD entry count and use relative instead of absolute offsets.  There
        is a large amount of information stored in these maker notes (apparently
        with much duplication), but relatively few tags have so far been decoded.
