Out of curiosity, with regard to video, what would be the difference between what you describe and a nicer version of the sort of processing used in (for example) some Axis security cameras? I guess the current method is just to capture a decent range and then process each frame to boost the gain on shadows and lower the gain on highlights, right? Sort of an extension of quick-and-dirty HDR on still photos.

Either way, this is the sort of stuff that has always interested me about photography and videography. The creative aspects are obviously the end goal for most people (myself included) but I've always been a sucker for the technical aspects of it...the craft to the art as it were. Nothing prompts me to pick up my camera and shoot some photos or some video like learning about some new tool or technique that I want to try out. It may be the mark of the eternal amateur but still enjoyable.



I'm not familiar with those cameras. But if they're using a conventional sensor, this technique yields qualitatively different results.
