Only half/One of the best angles i've ever seen Sydney from was heading towards the CBD over the ANZAC bridge one afternoon. The sun was setting behind me and casting a brilliant golden light on to the Western Face of the city, and all above and behind the skyscrapers was a dark, dark, dark black cloud that was just about to dump rain everwhere. Simply beautiful.
Also, I like looking across the Harbour from Kirribillis. the SOH on the left and SHB on the right just frame circular quay and the skyscrapers so well.
