It's very difficult to take candid portraits of children because they're moving around all the time.

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.

With Illum, we're able to start to customize that supply chain in a very deep way... to rethink the entire imaging pipeline.

I've always been very interested in the question of how computation can fundamentally advance the things that we can see. This led me to have a fascination with medical imaging, especially things like MRI and scanning, and eventually computer graphics.

I'm very candid.

Mark Horowitz and I built it onto an optical bench in the lab. We spent and eight-hour span putting this optical light path together.
