High Dynamic Range (HDR) photography has been quite controversial over the past few years. But, if you thought HDR photos had fans and foes, just wait until HDR video catches on.
The above clip from Soviet Montage is captured using 2 Canon 5D Mark II cameras shooting the same scene simultaneously with the aid of a beam splitter. One camera is recording at +2 EV and one camera is recording at -2 EV.
Regardless of how you feel about the HDR effect, you have to admit that these shots are interesting at least. You can also bet that a feature like this will be built-in to a camera within a couple of years or so.
