I haven't heard anything about this software around the boards, but I stumbled upon it while doing some research on Nik HDR. I've been using Photomatix for quite a while, but this caught my eye to see that it was based on making non-hdr looking hdr's.
Either way, I've been playing with the lite version, and I've got to say that it does a pretty nice job for being free. It's extremely basic...drag your files into the icon, watch the little dos window for a couple minutes, and find your final file in the folder you got your source images from. From testing it against some fusion exposure images in photomatix...that's basically what it is, but without any options, and they come out pretty damn good for free ware. Apparently theres an option for saving as 16 bit tiffs, but I can't figure it out.

Just thought I'd share if anyone was interested.
