I have communicated with Bill Radcliffe, the one who wrote the IPTC utility distributed with libtiff, and the author of the TIFF IPTC support in ImageMagick/GraphicsMagick and he believes that libtiff is correct in using TIFF_LONG. Given that he has been working in this area for many years, I am strongly inclined to trust his opinion on this.

ImageMagick/GraphicsMagick include byte-swapping code to deal with IPTC coded in both big and little-endian forms. The endinness is expected to match that of the TIFF file (based on TIFFIsByteSwapped()).

Bob,

Any insights based on the relevant specifications and logic, I'd love to read them.
