This is an image I made in Vancouver--it was my first set of long exposure cityscapes I've ever made. It was fun! The best part was seeing the changes various white balance settings made on the image. There is not one single color of light, so balancing for each of them is not reasonable, and also no fun. I like the variety of lights here.
Nikon D90, 50mm lens, f22, 25.0s, ISO 200. This is tripod work, of course.
