From Bruce Sharpe here comes a link to an article on cnet here about HDR video. Soviet Montage Productions of San Francisco has found a way to combine video from two Canon 5D mark II's, one over exposed and one under exposed into HDR video. While we wait for true HDR imagers, maybe someone will rediscover the techniques used by Technicolor for film and older video cameras of using a prism to split an image to 3 imagers with different settings or simply use neutral density filters. Video with dynamic range that exceeds the human eye can't be far off.
