First of all, here are some announcements re: the paradigm-shifting Lytro camera:

Secondly, here is my key question/reflection:


I wonder if this same type of thing could be done with digital video? What if you could take a video of a symphonic band and could zoom in on whichever section (strings, brass, percussion, etc.) that you wanted to? Or zoom in on strings on the first play through, percussion on the second play through, etc.
