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.
The reason we know as human beings that pictures have to be focused before you take the shot is because we know if we're not focusing our eyes on something that happens, then it's too late - you can't go searching in your memory to find it because that light never struck your mind.
We have seen amazing, creative and interactive pictures from camera owners, and I'm looking forward to the Lytro camera being available in Australia.
I am a very keen photographer. I have enjoyed taking pictures since I was a kid with my family, but I became more serious about it at university.
