This is probably one of my favorite photo’s i took at the Columbus Zoo with their light display. same tecnique. I put it on a shutterspeed on Aperture-priority mode. My shutter speed was 2 seconds. I had my dad push me in a wheelchair. I was in a wheelchair because i had ankle surgery and have no weight bearing privledges.Maximum aperture was 14. iso was 1250.
