This one was a bit rough to shoot. I was using my multi-gopro rig for this one so I could shoot multiple heights at once, and had to try to get all my shooting during the crossing signals *and* while it was clear of all traffic, leaving just a small window to be in the crosswalk each time. I stayed out of the middle.
I'd love to try doing this with a drone if I kept it high enough to stay well out of the way. I bet it would get much cleaner results.
