Question: A number of you should attempt to define the light field in your own words here. It's always good to read through a number of different definitions.

The way that I think of it is as follows. You have two planes (let's call them $A$ and $B$), one of which is emitting or reflecting light ($A$). For a point $p$ on $A$, the light field tells you what points on $B$ receive light from $A$ at $p$, and in what quantity. In other words, if you're at a point $x$ on $B$, the light field will tell you where the light is coming from on $A$ that is is hitting $x$. Am I on the right track?

I think the light field is a concept corresponding to a space. If I have a space, then the light field is a set, which contains all the light rays passing through the space.

I think of it as all the information generated by a 2d array of eyes each producing a 2d image.
