We arrived in the later afternoon and took the lift up one of the Supertree towers to the aerial boadwalk. The views are stunning but photography was problematic owing to the movement of the boardwalk due to people constantly moving along its length.
Security often moves people to the down lift after 20 or so minutes when there are a lot of people but we were able to stay longer as there were only a small number on the boardwalk.
While its great to be up there when the lightshow is in full swing it is also essential to be on the ground from a photography perspective. My photos here were taken with the camera sitting on the ground as I had no tripod.
I would definitely go back to Singapore just to see this amazing lightshow again, next time perhaps viewing it from the Marina Bay Sands Skypark.
