Photographer David Johnson decided that photographing fireworks the normal way was too boring. Instead, he refocused on the exploding fireworks at different points during a long exposure. The results more bring to life the Japanese word for "firework: hanabi, which translates to "fire flower."
"The technique I used was a simple refocus during the long exposure. Each shot was about a second long, sometimes two. I’d start out of focus, and when I heard the explosion I would quickly refocus, so the little stems on these deep sea creature lookalikes would grow into a fine point. The shapes are quite bizarre, some of them I was pleasantly surprised with."
