Slow sync or second curtain flash is an option. In fact, for someone who has not heard of or used something like this, it would be a great discovery. However, after a while, u will realize it will not be the best still. The best is still to set everything yourself and shoot in manual. But dun worry about what I say. Use slow sync or second curtain and if it works for you, that should be all. But if it does not, then try manual.
