An excellent site for EXIF info is http://www.exif.org/
I found that a good reader of EXIF tags is the one at http://www.takenet.or.jp/~ryuuji/minisoft/exifread/english/.
Exposure information is found in a private EXIF subdirectory. Such directories are not read and not listed by TIFFPrintDirectory. For that you need the pds routines of Poelman, part of the delivery of the library. And you may have to extend the tags recognized by using the routines of Ritter in directory 'contrib/tags'.
