Want Adjustable Depth of Field in Post? You Don't Need Lytro, Now You Can Use a DSLR

Joe Marine — Mon, 17 Dec 2012 16:54:52 +0000

Light field cameras could be the next big thing in photography and/or video, but as of right now, there is only one company selling anything that can achieve the affect: Lytro. If you have been wondering if this effect could be recreated with the DSLR you already own, the answer, as it turns out, is yes. The Chaos Collective, a group of internet futurists, has created a way to achieve the exact same effect as the Lytro camera with any DSLR, and has even created a way to embed the adjustable photos online.

Mystical Lytro Light Field Camera Now Allows for Equally Magical Perspective Shift, Plus Living Filters

Dave Kendricken — Fri, 16 Nov 2012 16:25:15 +0000

Lytro cameras already allow us to do something that, while (apparently) scientifically possible, seems to invoke more Gandalf than optical physics — which is to manipulate focus, dynamically and after the fact. By sampling the whole ‘light field’ within the field of view, they are truly fascinating iterations of the tools we use daily. This has some pretty interesting implications for the future of photography, not to mention videography — but Lytro isn’t stopping there. In fact, you can not only interactively shift your focal point, as you could before – but you can now, to an extent, alter the actual perspective of your shot as well, in real time — not to mention apply filters which also react in line with the company’s “living picture” aesthetic. For a demo video and some interactive examples, read on. (more…)

That Crazy 4D Camera Becomes a $399 Reality as RED Works on a Professional Motion Version

Remember that crazy 4D camera that lets you refocus after the fact? After the initial teaser, the Lytro has now gone official, with a $399 list price ($499 model also on the way) and “early 2012″ availability. A hands-on demo of the oddly-shaped consumer camera is after the jump, but as I asked in the original post, are there motion and professional applications of this technology? Well, turns out there are, and RED just dropped a hint that they’ve already got a prototype. (more…)

In Case You Missed the Crazy Future Camera That's Refocusable in Post, Here It Is

Years ago a reader emailed me about plenoptic cameras, also known as light-field cameras, which allow an image to be refocused after the picture is taken. Sometimes referred to as a 4D camera, this crazy technology is now headed to a consumer camera from new manufacturer Lytro. News of this development, which utilizes technology first seen in a 2005 Stanford research paper, hit the internet last week, with Lytro now taking reservations for the device. Check out the refocusable images in action, and let me know what you think — game-changer or gimmick? (more…)
