Lytro caused a lot of excitement among photography enthusiasts when it launched in 2011. Billed as the third evolution of the camera after film and digital, Lytro’s unique “light-field” sensor allowed snappers to “shoot first, focus later”, as well as other “computational photography” tricks such as shifting perspective or add 3D elements to an image after the photo is taken.

However, the Silicon Valley start-up’s first camera was aimed not at hardcore photographers, but at a mass market. The $500, flashlight-shaped device was described by the FT’s Chris Nuttall as “an amusement for now”, due to issues such as a small screen/viewfinder and counter-intuitive controls, even if he predicted the underlying technology was “likely to change photography radically in the long run”.

Three years and one CEO change later, Lytro is back with a new device, the Illum. It is aimed more directly at those snap-happy early adopters, professionals and “aspiring amateurs” who were most enthusiastic about its technology in the first place but perhaps found version one fell short of their hopes. Read more

Photography takes the same kind of leap as black-and-white movies to colour or music from mono to multi-track with the Lytro – a camera that captures light rays and their direction, allowing incredible manipulation of images after they are taken.

The subject of the latest Personal Technology column, the Lytro is an amusement for now, but is likely to change photography radically in the long run. Read more

There is a lot of excitement about Silicon Valley company Lytro and its new take on photography – its Light Field technology allows different parts of a taken picture to be shifted in and out of focus.

The company held a news conference in San Francisco this morning to unveil its first camera, which it said would go on sale next year, starting at $400.  A live blog of the event is after the jump. Read more
