In further exploration of the Canon SDK, I think it would be fun to play with focus blur. The repeatability of the arm and the Canon Camera being controlled by an app, would be a great way to conduct experiments in focus blur. Since focus blur on moving light is extremely hard to capture in fireworks (a very quick event,) I would be able to experiment with focus blur on LED lights indoors. I would perform this experiment on a few different shapes with various focal blurs and see what happens!
