Or bad, depends on who is asking or on what is someone doing. Lytro light field camera can capture a 4D pictures. Which means, means, the time will be no longer a secret. If I have the chance to capture the right scene, I could see some dinosaurs after I downloaded and I began to shift perspective. Or maybe I’ll see my self in a few or a more years. Exciting? Creepy? Who knows? Although this comment is a little bit ironic. who knows? There is a somehow plausible explanation. Light field camera sensor supposedly captures the light rays in an immense number of position, including time. There was a myth or superstition in some culture that said the photography could steal the subject soul. Maybe it was not a superstition after all.
Anyway, it is interesting and funny to play with the pictures from their website.
