As I mainly use slides, this might be a slight deviation from the main discussion. i have taken a few shots of the London street Christmas Lights using a hand-held camera with a Provia 400 film. Using any form of camera support in such crowded streets at night would have been rather difficult. Camera shake is evident so I can't claim that the result is exceptionally good. But I can say that it can be acceptable. Here are three examples from my flickr page for anyone interested
