a novel approach to photographic imaging is making its way into cameras and smartphones. Computational photography, a subdiscipline of computer graphics, conjures up images rather than simply capturing them. More computer animation than pinhole camera, in other words, though using real light refracted through a lens rather than the virtual sort. The basic premise is to use multiple exposures, and even multiple lenses, to capture information from which photographs may be derived. These data contain a raft of potential pictures which software then converts into what, at first blush, looks like a conventional photo.
I still don't quite get the talk about ray tracing. The part that makes sense to me, however, seems to explain it all: the camera has a wide-open aperture and an infinite depth of field on the main optics, but a bubble-wrap like plane of different lenses in front of the sensor, which thereby ends up capturing a fly-eye myriad of differently-focused fragments of the same scene. The software assembles a final composite depending on which of these you later focus on in post. It improves upon established focus stacking techniques because every image is taken simultaneously as a single exposure, at the cost of dividing up the sensor's megapixelage between them.
Something like that, anyway. I'm going to play Minecraft.

Nelson E. Ross’s “small booklet” sets out the principles of sending telegrams “in the most economical manner possible,” so you can take full advantage of a communications medium that “annihilates distance and commands immediate attention.”
Projects will always need management. And now with the tech gold rush it feels like there are more projects than ever with fewer managers than there’s demand for. But it takes too much time and money to go back to school full time so luckily the Project Management Professional certification training course is now 96% […]
If you’ve been blessed enough to avoid them yourself, you’ve definitely heard the horror stories. Late night, crushing out a ton of work, writing, coding, anything, then boom – your computer crashes. The battery blows, you spill water or coffee all over the place, or it just shuts down with no explanation, and you’re screwed. […]
You travel around a lot. It might be that jet set life from New York to LA to London to Tokyo, or it might be back and forth from the coffee shop to the office, or from the kitchen to the couch. Any which way, you’re mobile and that’s the way to live. When you […]
