TIFF Tag Reference, Private TIFF Tags

Private TIFF tags are, at least originally, allocated by Adobe for organizations that wish to store information meaningful only to that organization in a TIFF file. The private tags listed here are the ones that found their way into the public domain and more general applications, and the ones that the owning organizations documented for the benefit of the TIFF community.
