RED's Dragon sensor - 20 stop dynamic range

It's a sensor designed for a video camera. It would allow the user to shoot in a relatively dark room, then go into a brighter room (for example) without cutting and without having to change the exposure. The video would be graded in post to achieve the contrast levels required for (and exposure transition from/to) each of the locations, allowing for a huge amount of control.

It would also be useful for shooting backgrounds for effects shots by allowing compositors to match lighting between full DR real/CGI elements prior to final grading.

There's a big difference between still photography and movie work!
