Lytro wants to change the way we take photos by introducing the concept of ‘living-pictures’. A ‘living-picture’ is a picture that the viewer can change the focus of it (check out the sample images on Lytro’s site). Lytro uses a technology based on (4D) light-field photography, which capture not only the amount of light at each pixel, but also how much light arrives along each ray. In order to capture the additional data, it uses more pixels, which means lower picture resolution. The innovation behind Lytho technology is in the ability to capture the ‘living-pictures’ in a single shot on a similar form-factor camera. Another advantage of the technology is the ability to shoot a 3D images from a single lens using a single shot. Lytro CEO Ren Ng said that he expects to see the first Lytho camera in the market by the end of the year, but no additional details are available at this point.
