Hi,

I've been playing with the dual photography concept:
http://graphics.stanford.edu/papers/dual_photography/

And I've come to these images:

1.- Primary image. Standard light and camera
2.- Reconstructed dual image. Shine the light over a tiny portion of the
scene, create a lot of 1x1 pixel images and put them together as a mosaic.
Camera and light layout as in #1
3.- Reference dual image. Camera and light exchanged

Ideally, 2 and 3 should be identical. 3 looks somewhat distorted... there
must be something I didn't take into account. It's also clipped, because
the "photodetector camera" was not wide enough to capture light from every
possible direction. And it's too noisy, that could be due to incomplete
antialiasing.

I'm sending the source code to p.b.scene-files.
