Do you like starburst patterns, like around the lights in the shot below?
They are easy to get. The secret? Use a small aperture. I shot the shot below at f/11 – that was enough. The image took 15 seconds to shoot at low ISO.
Q: Why low ISO? Surely you should shoot with high ISO at night?
A: Only if you are attempting handheld shots. For quality, use low ISO and a tripod!
