...If you’re at all familiar with the Nik interface from any of their other plug-ins, you are ahead of the game because the new HDR plug-in uses the same interface.
The plug-in is designed for people who don’t want to have to tweak a whole bunch of sliders for an hour to get a good result. It also has a bias toward more natural-looking HDR shots, which personally, more closely matches my style.
Keep in mind I am discussing (with Nik’s permission) what I’ve seen so far. There could be changes once the program goes into full beta and finally goes gold for retail....
