I'm trying to work out how to read and write IPTC tags into TIFF images. I've downloaded the specification for IIMv4 from http://www.iptc.org/download/download.php?fn=IIMV4.1.pdf and I think that's fairly clear how an IPTC record is structured.

But... How does this relate to the libtiff Tag Reference guide at http://www.awaresystems.be/imaging/tiff/tifftags.html?? Is there a private tag description for the IPTC information or is it held inside the Photoshop Tag (ref 34377)?

Am I missing something obvious?

Thanks
Gary
