I think this is basically almost every photo that Myers has taken. What I do when I'm taking pics for a gallery is to try and get three times as many as I need, that way I can just bin the bad/blurry ones without missing out important pics. In the dark environments you have to use a pretty slow shutter and blur is inevitable since you can't always control the subject.
