I've shot at a party at night recently. I've used mainly multi point (continuous) tracking as it makes more sense, as random events may come and go.
My friend suggests that I should have used single point to increase the amount of images worth keeping. I don't do that but I do bracketing, and it improves my keeper count, as well as just taking multiple shots. If Single point AF preferred when you're shooting at such events or is it more of a personal choice?
