The optics of the camera obscura ha­ve faithfully served photographers for ages. The recipe has been simple: a lens, aperture, dark box and something to record the light.

But the camera as we know it is changing. A revolution in digital imaging research could surpass the camera obscura in almost every technical way: resolution, size and energy efficiency. It’s called computational photography, and it stems from the idea that if you can capture visual data instead of a true image, then the picture can be reconstructed with software.....Continue Reading
