  Thanks for all the feedback, although I have to admit I'm a bit
  overwhelmed.

  No chance. I do not consider proprietary, de-facto "standards" to be
  standard, *especially* if they were written by Microsoft. Give me
  something that has been written by the IETF or some other standards
  body. Think interoperability.

  Thanks, that was the most useful bit of information I heard.

  Basically, I'm scanning a bunch of slides and burning CDs. I'll be
  (later) processing the scans with the GIMP and other software on
  Linux. I'm making copies of the CDs for a friend who probably uses
  Photoshop on Windows, and someday I may wish to give the images to a
  graphics professional.

  I may be using the term "raw" incorrectly--I just mean that that the
  images have not gone through any laborious post-processing after
  scanning. I am using an auto-adjust button and tweaking the contrast
  in Xsane which performs the scans though.

  OK, so I should use TIFF. Now, on to compression.

  Xsane, via libtiff I'd imagine, provides several compression
  schemes: JPEG DCT, and something called "pack bits". Is the JPEG DCT
  compression LZT in sheep's clothing or is this something I could use
  that would be universally accepted?
