In a recent tutorial Animating a Still, we used tracking data from a real hand-held camera to give our still image a natural look, as opposed to using a mathematical expression like the wiggle. This gave our footage a natural organic look that would be difficult to achieve with expressions.
Then I thought I would try a similar experiment utilizing a real optical rack focus.
So I filmed a dark square while performing a real rack focus to see if I could extract the information inside of after effects to use with a 3D camera.
And since I’m actually posting this, you can assume it worked, unlike my perpetual motion machine that you will never hear about again.
