Re: Future of photography: Imaging by light vector recording.

What does "light vector recording" even mean?

This method can record two very important details on the light: color and intensity; together with the position they fall on the light sensitive material, an image can be made.

Color and intensity define a perfectly good vector.

But now a university has constructed a camera that could record light in the form of a vector, that is, information about its color, intensity and direction of travel.

"Direction of travel" is well known -- towards the camera. You know just where because it's an imaging system.

with 3D vector of lights recorded, any 2D plane can be constructed to produce a photo at that focus. Imagine a sensor capable of recording all lights in all directions around you, and store them in vector form; from this massive collection of data, all possible photos that could be taken at that point with a traditional camera can be constructed.

OK this sounds like plenoptics. You're selecting a tiny fraction of the total information collected, but you have to collect all that information because at the time of capture you haven't decided which fraction you want to use. It's competing against the "standard" approach, which is to decide beforehand and maximize those information resources towards that decision.

scared ? excited ? share your thoughts.

Why the breathless enthusiasm right now? A hundred years later we're still stuck with the information bandwidth issue. Bandwidth has gone up but not nearly as much as expectations -- that is, from a photographer's perspective, to get something acceptable, instead of proof of concept. We're nowhere near that threshold.
