As promised here are a couple more Lytro examples. These show how the focus can shift on an image. As you can see the focus can be on any object or place in the picture... Means thinking about images in a new way. The window shot is so much like we actually see that it is amazing.
More about Lytro from their website:
Lytro was founded in 2006 by Executive Chairman Ren Ng, whose Ph.D. research on light field photography won Stanford University’s prize for best thesis in computer science in 2006 as well as the internationally recognized ACM Dissertation award.
In 2012, Lytro released the world’s first consumer Light Field Camera which offers photographic capabilities never before possible, such as focusing a picture after it’s taken, changing the perspective in the picture and creating interactive living pictures that can be endlessly refocused and enjoyed by friends and family online. Lytro was named one of Time Magazine's 50 Best Inventions of 2011, was Popular Science's Innovation of the Year, 2011 and took home the Last Gadget Standing Award and Best of Innovations Award for Digital Imaging at CES in 2012.
