Jim,

It would be helpful to see a tiffinfo report on the file to know if
there is anything out of place, but it sounds ok.

However, this is a TIFF configuration that is unlikely to be supported
by many "picture oriented" TIFF viewers.  TIFF is very flexible, but many
applications supporting TIFF do not support the full variety of configuration
possibilities.  This will count as an awkward one for many viewers.

Best regards,
