So, here is the shot. The one that cost me a burned arm. My wife has completed her editing and allowed me to post. Whattaya think?
I was flingin’ sparks from the left. It was a thirty second exposure. What that means is that real life didn’t look quite like this- to the standing observer, the sparks weren’t in long clean lines, but were individual sparks falling along the paths you see here. And there weren’t this many all at the same time. What you’re seeing is a whole half-minute of life frozen into a single image. Also, the sky was black to everyone standing there. The camera collected all the light in the sky the whole time and that makes it seem like it’s still blue to the naked eye.
