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

The individual data points of life are much less predictable than the average. Here’s a simulation that shows you how much time is left on the clock.
So far we’ve seen when you will die and how other people tend to die. Now let’s put the two together to see how and when you will die, given your sex, race, and age.
There are rules—usually for specific chart types meant to be read in a specific way—that you shouldn’t break. When they are, everyone loses. This is that small handful.
I wanted to see how daily patterns emerge at the individual level and how a person’s entire day plays out. So I simulated 1,000 of them.
