Blue hour. We all know this is the magic time to photograph cities: when the sky has still some color left in it and the city lights are already on. The only problem with Singapore is, due to the latitude of just a couple degrees, the sun dips behind the horizon very quickly and the blue hour is extremely short -- it's more like a magic quarter.
But if you manage to use this short window of opportunity, the colors will just blow your mind. (2013-02-09 Marina Bay Area, Singapore)
