I have never tried to take fireworks until last night. We had a neighbor that shot some off and we can see the top of the highest shot from a park near by. I even took some of the cars coming up the road in the smoke. The wind wind was not blowing so the smoke just hung in the air giving an erie look.
All were taken hand held an set on 1600 ISO @1/20th.
This was caught just at the right time, the explosion. It's one of those that just make super loud noise, like the warning shots the big displays give off.
