Really enjoyed going down to Vivid and taking some shots especially of the illuminated office building overlooking Circular Quay with their great colours. Now if you are really keen on photographing urban night scenes there is a good tutorial I have come across which talks about how to create more vibrant photos using luminosity masks in photoshop on the Digital Photography School website by Yaopey Yong.
The whole point about this article is to help you to correct over exposed highlights due to using a long exposure. My shots were all taken with a tripod on a Canon 5D Mark 111 and the mirror lock was enabled to avoid any movement with a 1-second exposure.
