Most cameras only capture a single plane of light. Well this one captures the entire light field, meaning you get all the light travelling in every direction on the photo. So what?
So you can change which point you focus on after you’ve taken the picture, which is great news if your friend did something hilarious in the background. You can also swap between standard view and 3D.
Basically it opens up a whole new set of options for your snaps, which’ll help you look like a better photographer. And that’s worth £250 of anyone’s money.
