This is a landscape photo of downtown Sydney skyline in Australia at dusk. The purple gradient night sky is dotted with scattered clouds, and the lights of high-rise office buildings are lit up one after another, with warm yellow and cool blue neon lights interlaced. The foreground is the calm water of Sydney Harbour, which smudges the colorful lights of the waterfront buildings into soft colored light bands. The picture not only shows the prosperous vitality of Sydney as an international metropolis, but also presents a relaxed and quiet atmosphere.
