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.

Lured by the internet’s pervasive insistence that it represents a superior, more comfortable typing experience, I recently went back to an old-timey mechanical keyboard. This was a mistake. I am now a hamfisted ASCII jazz disaster.
SpareOne Emergency Phone is a basic cellphone powered by AA batteries. This gives it a relatively short time on a charge, but means that it will have a charge after being stuffed in a drawer or glove box for months. I came across this during my search for the perfect basic phone, but be warned: […]
Low-cost carrier Easyjet has prototyped “Sneakairs,” a pair of shoes that have small vibrating motors and Bluetooth links; they work in concert with your mobile phone’s mapping app, buzzing left or right when it’s time to turn, and twice if you’ve gone the wrong way.
Jared Sinclair developed the RSS reader app Unread, which made $10,000 in its first 24 hours on the iOS market. And we’ve all heard the story of Flappy Bird developer Dong Nguyen, whose creation was reportedly earning $50,000 a day at the height of its 2013 explosion. While those are rare examples, they’re also testament to the […]
