Status:   

It seems the concensus is that libtiff is really great for reading and 
writing TIFF files, fairly useless in reading EXIF-encoded TIFF files, and 
completely useless in writing EXIF-encoded TIFF files.  Equally bad is that 
libtiff expects a valid image in the first IFD, and so is again fairly 
useless in parsing EXIF-encoded JPEG files, and completely useless in 
writing them.

Alas, I require the ability to read and write EXIF information in both TIFF 
and JPEG formats.  I've given up on libtiff and begun using libexif for the 
JPEG side of things, but it is the canonical example of the actively used, 
yet completely undocumented library.  Hopefully, my need to support TIFF 
will wait long enough for libtiff to catch up.
