Embedded above is a preview of where we'll be after day 5. We've still got a few kinks to work out, and we're going to be adding some 3D motion graphics, but the 3D 360 video is pretty darn seamless.

This series is going to be based around the 18-camera rig, but the vast majority of the content will be applicable to any multi-camera 360 setup. If you're reading this and getting excited to buy and assemble your own 3D 360 rig, I implore you to just wait a few more days. I've been working on an improved version of my prototype that requires half as many cameras, and I think you'll be as happy with it as I am.

So, let's get started!

If you've got a headset, you should really take a moment to check out the 3D side-by-side video linked above - with a little pixel-pushing to eliminate our unavoidable stereo stitching errors, it's a nice-looking and promising shot.

Initially, I was concerned that there wouldn't be enough light to shoot this indoors at 60fps - remember that I'm shooting 60fps to sync cameras more precisely in post, and that a camera captures half as much light at 60fps than at 30fps. Fortunately, the positioning of the apartment and the time of day gave us ideal lighting conditions - plenty of cool blue diffused light, the sun casting dramatic shadows on the buildings outside, and pretty great visibility for a megacity like Seoul. I especially love the contrast between the warm light from inside the apartment, and the cool blue light from outside - this happened naturally, with only minimal color correction tweaks.
