Long-term (2 weeks) timelapse installation in Philly. The 2nd camera is the backup. There were no beams or poles or railings to mount the cameras on this rooftop across the street from the site … so they had to be tripod mounted. The tripods are weighted down, and covered in plastic in case of rain. They are tied with rope to a big AC unit so they won’t blow off fhe roof. Not ideal, but we improvise where needed. I’ll be back in two weeks to see what has transpired.
