Z-depth photography
Hi I was wondering if someone could help me find a video I saw a while ago.
It was about a technique some people at I think a University somewhere in the UK developed to capture depth/height information using just a standard digital camera and flash.
I can't remember all the details of how it worked (I think the girl in the video was super hot so I couldn't concentrate) but I think it was along the lines of, if you took two photographs one in really even ambient lighting and one in the same lighting but with a flash on the camera. You could then compare the two and get depth information from how the flash attenuated?
I've looked all over for that shiz and I can't find it again. I didn't see it here but I thought someone else might of heard of it.
Cheers.

Awesome, that is the one I was looking for thank you!
Also has a link to this...

..with a more detailed video and the Siggraph paper.
Have to wonder how well it works in practice their tests certainly look very convincing. If I could afford a damn camera I'd try it!!!:poly127:
What is this HDR technique you speak of ArtsyFartsy?
I also read a paper about some coded aperture technique but it could only separate very broad areas of depth.
