I’m not enough of a camera techie to know exactly how this works but this Light Field Camera, due to be released in the wild later this year by California startup Lytro looks incredible.
Essentially, unlike regular or digital cameras, it captures all the light rays in a scene and enables you to shoot pictures faster because – get this – you focus after taking the picture, allowing to change depth of field and other tricks to produce sone astonishingly lifelike images. Have a play around with this Lytro image below – click to refocus and double click to zoom – and check out their website. No word yet on pricing.
