This doesn't hold a candle to Keith's (forgive the pun) in terms of technique or travel, but here it is anyway.
From the Muju Firefly and Fireworks Festival, the same night that gave me the Silk Purse from a Sow's Ear challenge shot. Nearly the only one that came out in something like focus, whether that's my equipment or skill I don't know, but I'm betting a combination of the two. Still, as fantastically crowded as it was that night, I'm glad I got this.
These two people were lighting the jute-like fireworks from this little portable campfire. The fireworks hung from a wire strung across the river from pulleys and they fed them out bit by bit as they were lit. I have lots of shots of falling cinders, but I thought the people behind them were more interesting.
