We went to take a timelapse of the sunset of Sydney Harbour with the city and Opera house and bridge in the background, moments after taking the one using the camera slider the cruise ship that had been in the harbour for New Years started leaving and we managed to get another quick timelapse of it leaving. It took about 20 minutes to reverse and depart and we just captured it as it left.
Camera: Canon 5D MkIII
