The Bundeena Wharf after sunset. People catch a 70 year old ferry to cross to Cronulla. The only otherway out is by a 30 minute car drive through the Royal National Park.
I used a 2-8 stop Vary BD filter on my Canon 5D with 16mm-35mm Lwide zoom. Tripod and 30 second exposure at F8
There was some nice white light for the forground from a standard light behind me.
