On the personal side, I was rock climbing and taking pictures with my friends. We took all sorts of portrait and action pictures, and I was thinking at the time that these are inherently difficult to focus correctly.

Yes, we are a producer of cameras, but we understand that at the end of the day, you have to make photos in software. A lot of companies focus on the camera side, and a lot are on the software side. There's a chasm between the two.

Camera 1.0 was film. Camera 2.0 was digital. 3.0 is a light-field camera that opens all these new possibilities for your picture taking.
