Lots of things in the background. From left to right - Centennial Tower, Millenia Tower, North Tower, Suntec Convetion and Exhibition Centre (white sail roof), South Tower, Marina Bay Sands (near the sea), Marina Bay Financial Centre (blue skyscrapers, far right). There's also the Esplanade Theatres and the white column of the World War II Memorial on the right, and part of Raffles Hotel at the bottom right.
View from The Pod at National Library. I was photographing an event there and had plenty of down time.

Technical information:
- Nikon D600, 28-300mm f3.5-5.6
- At 28mm, f8.0, ISO 100, 1/180 seconds
- Aperture-priority, automatic ISO, center-weighted metering, automatic white balance
- Picasa: Straighten, crop, auto contrast, fill light, highlights, increased color saturation
With landscape photos like this, you can usually boost the color saturation to make the colors more intense. It's harder to do when there are people in the photo because then their skin tone will look artificial.
