High dynamic range photography If you're into photography you should investigate high dynamic range imaging. Some good examples can be seen on flickr.

I am an avid risk player but am tired playing against the computer. Are u aware of any online playing? I hear Lux is very much like Risk. Could u be so kind as to point me in the right direction to get hooked up for on line play? Thanks Tony | | |
| Wow, that makes my heart race. It's like virtual reality reality. It's like my eyes haven't been giving me the best view of life. | | |

It's not inconceivable but would require a bit of processing and some fancy video capture equipment.
Let's say you wanted to see these images at a high frequency so that you wouldn't notice any flicker. I'll go with 100Hz (100 images per second), which is pretty high (for reference, your computer monitor is likely set at 60-90Hz). You capture an image and bracket it (capture and image going one stop up and down to get different contrasts). So now you have 3 images that you would combine into one image. To get 100 HDR images per second you need to take 300 images per second plus the ability to combine 3 images into one HDR image every ~3 ms. And that's just for live HDR...
If you wanted to do filmed HDR, you would need to use one camera that captured film (typically 24fps) but added two other contrast settings for each frame. So you'd need a 72fps camera that could switch contrast faster than every 13.9ms. You could combine them after the film has been captured and there's no limit there. Of course, rapid movement would be an issue.
Alternatively, you could use three cameras filming simultaneously, each one set to a different contrast. This has the added benefit of eliminating the movement issue. And, as a bonus, if you put a distance offset on them, you'd even be able to create 3D HDR movies.
