We watched Independence Day fireworks across the valley from north Lehi mountainside. I didn't have a tripod, and wasn't sure which settings to use. I've seen images of fireworks taken several different ways using a variety of settings, and I quite honestly like them all. I don't think there's really a "right" way to do it, it's a matter of which style you like... and what is available to you at the time - including your positioning and WHERE you're actually able to take photographs from. This is what I could do "at the time."
