Topic: Promising new tone-mapping software
It's PC-only at this stage, although a Mac version is in the works. (I'm running it via Parallels on a Mac).
30 day trial is available, so it costs nothing to try. I like it overall - image quality seems high. I had a few minor niggles, which I've sent to them to help improve the application. Also, you can't open a large file unless you are running a 64-bit OS.
It does more than just tone-mapping but you can see for yourself on their homepage.
Let me know what you think.
