I've done a lot of work with OpenEXR at previous $job so I can talk you through some of that stuff but, to be honest, we were using NothingReal Apple's Shake and/or custom tools to do most of our manipulation.
Fortunately, since Apple have decided to give up on Shake it's now dropped down in price to about $200. Unfortunately that's only for Macs. Unless things have changed the Linux version is still about $4000 per licence.
Also, Shake is unlike any Image Manipulation program you've ever come across - it's designed for compositing over a timeline and the interface is a DAG. You drop IO Nodes ((multiple) FileIn and (multiple) FileOut) into the script and then start dropping in other nodes (image mult, blur etc etc) in. Writing your own plugins is pretty easy and very powerful - they can either be a collection of collapsed nodes or written in C++.
Open Source wise there's a couple of GPL compositing tools that might help - Cinelerra (of which there are several different forks - it's a bit complicated) or the tool previous known as
( ... )
Brad, I forwarded your post to a friend of mine who has a Ph.D. in CS with a specialty in imaging, and he also recommends OpenEXR for HDR rendering. As far as tone mapping operators are concerned, he says that there are many to choose from, that they're essentially task-dependent, but that the most common one is probably Ward's operator.
He said that one of the leading guys in this field is Paul Debevec, whose site is at http://debevec.org/.
Since I always want to recommend NetPBM, I googled [netpbm hdr], and that brought up multiple independent mentions of psftools. One of them is on the “Other HDR Software” page of WebHDR, which seems to be a web-based HDR compositor.
I'm not familiar with HDRs on Linux, but some pointers for Windows and Mac through my experiences:
-PhotoMatix is the best tool to create HDRs, if you happen to use PhotoShop, I have found that color are not as vivid -for moving subjects, you can just shoot RAW, open it up in PhotoMatix, it will adjust the exposures, and create an HDR from just a single RAW, not as good as shooting three

Hope that helps a bit.
