I was going to suggest the LM7806 like CharlesL suggests. It can handle 1amp of current draw continuous and over 1.5amps for short bursts. They do draw a few milliwatts continuously but that's not much for an external battery. You could add a 470uf capacitor on the 6V side to give you a short burst of higher current for a flash or something. If you need more power than the LM7806 can deliver, there is 317 that deliver more power but involves more circuitry.
