Hello Gordon,
Thanks for the post on HDR imaging!
For the curious, here is a link to the work of Paul Debevec and
his team who developed this technology.
http://athens.ict.usc.edu/Research/HDR/
There's a link on the page for the HDRShop software that is
available for download.

Also, the mkhdr software for creating HDR images from photographs
is available for download.

best regards,
Phillip
