I've been meaning to address this Lytro thing since it hit a few weeks ago. I wrote about omnifocus cameras as far back as 2008 , and more recently in 2010 , and while at the time I was more interested in the science behind the systems, though it appears that Lytro uses a different method than either of those. Lytro has been slightly close-lipped about their camera, to say the least, though that's understandable when your entire business revolves around proprietary hardware and processes. Some of it can be derived from Lytro founder Ren Ng's dissertation (which is both interesting and readable), but in the meantime it remains to be shown whether these "living pictures" are truly compelling or something which will be forgotten instantly by consumers. A recent fashion shoot with model Coco Rocha, the first in-vivo demonstration of the device, is dubious evidence at best. Read on for more detailed reservations about this admittedly exciting device.
