I love to take photos of Cities at night, especially of those with skyscrapers with a waterfront. The city lights always show up nicely as colourful reflections in the water. The best time to take night photos is the blue hour, which is around 20 to 30 minutes after sunset. You only have a window of around 15 to 20 mins to do it! After that, the sky turns dark. These photos are of the Singapore City skyline, taken in the Marina Bay area.
