Photographer David Johnson took long-exposure shots of fireworks. Fireworks already leave trails when they go off, the long-exposure versions create a spiky ball effect. Pretty. [via]
That’s a combination of zooming and long exposure.
Thanks for the post Nathan! These shots were entirely in bulb mode on the camera, where I’d hold the exposure open long enough to capture the explosion and that’s it. The camera would also be out of focus. Once I heard the explosion, i would simply refocus the lens so the light would converge to a fine point, hence the bizarre shapes.
How would you know when the camera was in focus though? Really interesting technique!
@Dave, I think the bottlenecking you can see near the tips is the result of perfect focus being attained and then overshot just slightly—it lends a nice organic aspect in my eyes and also implies that David didn’t need superhuman focusing skills for this technique.
Fireworks can become a paintbrush if you wish them to be. http://justsitback.deviantart.com/?rssQuery=gallery%3Azenmaterialist%2F39077029&s=8%2C3%2C0
