Anyone who does a lot of photography knows that the right exposure can make all the difference in the world. Taking a picture of something in motion requires a long exposure, so if you've ever wondered why your fireworks photos never quite turn out right, your shutter speed could be the key. Photographer David Johnson decided to put a twist on the classic long-exposure fireworks photo.
Normally, when people take photos of fireworks displays, they just set a long exposure for somewhere over 3 seconds or use bulb mode to gauge the exposure time by sight. Pretty simple, if you know what you're doing.
By refocusing during the shots, Johnson was able to uniquely capture these strange and utterly beautiful photos, which make fireworks look more like flowers or sea urchins (sky urchins?). And this is done all in about 1 second, 2 max.
"Each shot was about a second long, sometimes two," Johnson told Colossal. "I'd start out of focus, and when I heard the explosion I would quickly refocus," giving them depth and volume.
There are tons of cool things you can do with long-exposure photography. It makes for awesome photos of moving water and stars, and for something a little more fun, try using long exposures to make light paintings with flashlights or sparklers.
