My understanding is that the camera's file format is essentially a stack of JPEGs and a depth map. That's how the camera can do it's own refocusing without needing a huge processor. It's not generating the image from the light field, it's combining regions of a series of JPEG images.
I was really disappointed when I found that out. I thought the software on the computer was to process the raw data, but I guess not.
I still might be interested, but the the form factor is odd. Worse is that since they decided to go with that shape, they had to make the screen very very tiny.
It's an interesting product, considering it's the first of it's kind on the consumer market. I hope there is a version 2, because I think it could be very interesting. If it could shoot video, that could be pretty fascinating.
Heck, tell other people how to use the format. A series of focal planes and a depth map? Seems like hackers might be able to come up with some pretty fun stuff.
