Beautiful long exposure shots of fireworks by photographer David Johnson. Taken at the International Fireworks Show in Ottawa, Canada, Johnson describes his technique to the good folks at Colossal:
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.
