Some cameras actually compress the raw data BTW. I think Nikon does
that since nef (raw) output takes less space then tiff output.
The advantage of raw is that you get _all_ the data and not processed
data, so you get all the information. You can also reprocess it if a
better algorithm comes out later.

There is also a plugin that allows using draw to open the raw files
directly in the gimp. That should rival the Nikon capture software.
