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.
