It's used to properly expose the background, while also illuminating the foreground subject. The flash fires when the shutter opens, but the shutter stays open long enough to properly expose the background, which can be several seconds. (This is called first-curtain sync. If the flash fires at the [i]end[/i] of the exposure, just before the shutter closes, it's second-curtain sync, which can be used for a different effect.) If the camera or the background moves during the exposure, the background will blur, but the foreground subject will appear frozen. (If the foreground subject is somewhat lit to begin with, it will also leave a blur around the frozen flash image, giving the impression of motion.) However, with a simple long-exposure shot like lan is trying, everything will always blur. You can't move the camera and have parts blurred and parts not. The darker areas appear less blurred simply because brighter areas are more readily exposed, having a longer impact on the image. I'll see if I can create some examples later tonight.
