Another interesting part of the pfs project is "pfscalibration":

  http://www.mpi-inf.mpg.de/resources/hdr/calibration/pfs.html
  http://www.mpi-inf.mpg.de/resources/hdr/calibration/

This is a tool for taking a series of bracketed shots and assembling 
them into a single high dynamic range image.  It even reads EXIF 
data to determine the relative exposures so you don't have to enter 
it manually.

I haven't had much time to play with this stuff, but have built 
packages of everything for fedora linux:

Sorry, no windows binaries (though it shouldn't be too hard to make 
some with MinGW for somebody with a bit of experience).
