Lytro changed photography some years ago when it introduced light field photography technology. At that time Lytro introduced pocket digital camera that has adjustable focus that you can adjust afterwards. First lit looked like just a gimmick, but it seems that the idea has got wider interest that just this one product: several smart phone manufacturers are playing with re-focus after shooting options (they use different technology to get similar looking results).
The first Lytro camera was a small pocket camera, a product range that has increasingly gone unfashionable when practically all smart phones have at least semi-decent digital cameras in them. Lytro changed photography. Now can it get anyone to care? article tells that now Lytro is trying a comeback on the digital camera markets with a new Illum camera that has a DSLR shape, better image quality and improved re-focus options.
Lytro’s ultimate, simplest goal is to turn the physical parts of the camera — the lens, the aperture, the shutter — into software so it would take nothing more than a cheap lens and a sensor to build a light-field camera. Interesting to see that comes out of this development.
