This blurb cut/pasted from the above URL:

  The files coming out of a pretty much all Digital cameras are in the
  Exif flavour of Jpeg files. Exif files are for the most part Jpeg files,
  but start with a different header block, and contain additional data
  sections with camera settings, as well as a preview thumbnail picture as
  part of the Exif header. Most editing / viewing software just skips past
  the Exif header and ignores it outright, so you normally don't notice
  its even there.

  Because I am interested in photography, I am always curious just exactly
  what settings my fully automatic digital camera actually did end up
  using. There's a few programs out there that can parse some of these
  headers, but I couldn'd find one that I could compile to an executable,
  and none that actually figured out what the camera settings were from
  the various confusing ways in which the fields can be expressed. Parsing
  the data of interest out of an Exif header is not straightforward. There
  is a large number of ways that simple data such as shutter speed or
  aperture setting can be expressed in inside of an Exif header. It can be
  an integer of various forms, or a fraction or floating point, which must
  subsequently be raised to a power to get the true value. Then it can be
  stored big-endian or little endian, and there are different fields for
  expressing the same values! It sounds like complete eveolutionary
  anarchy, but I think its just a comitee designed spec. With all its
  complexity, interestingly enough, plain text ASCII would both be smaller
  in size and easier to parse! So I wrote this command line driven program
  to parse through the little file system in the Exif headers and extract
  the stuff I really care about
