Excellent to see this work done. The cost of the camera is beyond mere mortals and it is huge, but this is coming to us all in a not so distant future. Its only a matter of time before we have true HDR Video devices that can tackle difficult exposure issues that exceed current day sensors.
Check this video out!!! Amazing results!
I’ve toyed with pseudo HDR Video myself, but nothing real time. This was created with a Nikon D3 shooting brackets one after another, then tonemapped and tweaked in post to create a video like tilt.
