Lytro says its light-field camera, due to ship later this year, will let people change the focus of their photos after the fact.
A start-up called Lytro hopes to revolutionize photography by selling a camera later this year that lets people focus their images after the fact.
The technique used is called light-field photography, and it’s been an active area of research for years in the optics realm. With it, lens and image sensor technology doesn’t focus on a particular subject, but instead gathers light information from different directions; processing after the fact means different aspects of the scene can be recreated.
