HDR Video System Unveiled by University of Warwick
An obscene exageration of HDR
Although not available in a consumer product yet, research on High Dynamic Range (HDR) video coming out of the UK’s University of Warwick shows great promise for dramatic improvements in video image quality:
The new system captures 20 f-stops per frame of 1080p high-def video, at the NTSC standard 30 frames-per-second. In post-production, the optimum exposures can then be selected and/or combined for each shot, via a “tone-mapping” procedure. A process called Image-Based Lighting can also be utilized, in which computer-created objects can be added to real-world footage.
At this point the system captures a massive amount of data, 42GB per minute, for processing by post-production software. A huge investment in signal processing hardware will be necessary before a technology like this will be able to make its way into your next family camcorder.

The fact that the latest high-end Nikon and Canon DSLR’s can shoot 1080p HD video doesn’t tell the full story about the quality of the video they shoot. Some of the reasons why they suck for Video:
YouTube started with 480P, went to 720P, and it has
