Dual photography? Not easy to understand…
“Let’s say there’s some hot naked chick standing by a window, except she’s facing away from it so all you can see is her back. She’s watching NBC.
Luckily, you’re the president of NBC. You make a phone call and tell the network to interrupt programming and instead send out a video that illuminates each pixel, one at a time, in order.
While this is going on, you record the wall behind her TV. Your crappy video camera has only a 1×1 pixel resolution, but this doesn’t matter. Do a bunch of math based on your recording, and you can reconstruct an image of what she looks like from the TV’s point of view. If her TV has a 1920×1080 resolution, you get a clear, 1920×1080, hi-res image.
So see? Without this technology, you wouldn’t get to see what her boobs look like.” (raldi at reddit)
The official video shows it up visually, especially at the end. Sounds amazing!
