I thought it came out rather well for a non-tripod time exposure. It was the last frame on the roll of Kodacolor 400, I didn't have a tripod, and no tree to lean on to add stability to the shot, so the fact that it came out at all is amazing. And yes, they actually did fire simultaneously, which I think surprised the Cap.. Wish I had more frames on the roll, but you take what you can.
The night shot is MUCH more impressive than the day shot...
This is your work!
It is a darn dramatic shot.
I love the reds and the smoke.
