Adafruit builds Raspberry Pi-powered light painting rig, takes trippy photos
Taking long exposure photographs at night and painting within them using an iPad may be old hat, but building your own light painting rig? That could earn you some serious geek cred, and according to Adafruit, it isn't even all that hard. In a new walkthrough, the team fashioned such a contraption using a Raspberry Pi, a python script with under 60 lines of code, some open source software and a handful of electronic components. Not satisfied with the typical light wand, they decided to spice things up with a circular fixture built from PVC pipes and a hula hoop to hold the ribbon of LEDs. After being attached to a bike and paraded around at night, it created the 3D effect in the masterpiece above. If you're itching to make your own works of art, check out Adafruit's tutorial at the source link below.
Visualized: Stunning long-exposure 'star trail' photo taken from the ISS
Ever wondered what goes on up at the International Space Station? We like to think it's all floating around and eating freeze-dried steak. Astronaut Don Pettit decided to take a break from his no-doubt mundane routine and capture the spectacular image you see above. We say image, it's actually multiple 30-second exposure snaps layered on top of each other. Needless to say the result is both humbling, and hypnotic. Best of all? There's a collection of them, waiting to steal your afternoon with slack-jawed wonderment. Hit the source for the mind-melt.
Guest Post: Long exposure WoWtography
This article has been brought to you by Seed, the Aol guest writer program that brings your words to WoW.com. Long exposure photography is an intriguing photographic technique that involves slowing a camera's shutter speed, thereby allowing light more time to strike the film. The technique often produces otherworldly images in which there is a sharp contrast between stationary and moving objects -- perhaps you have seen long exposure photos of cars at night, their headlights melting into long streaks of color. Because long exposure photography often reveals hidden patterns, its applications can go far beyond generating simple eye candy. Last summer, I had the opportunity to do research on interactive digital media (read: video games) at the University of Rochester, and I thought it might be fun to try some long exposure photography within my favorite game, World of Warcraft. Rather than do real long exposure photography, however (difficult when one has no camera!), I opted to emulate the effect using video clips captured with Fraps and processed with a program called Exposure. Both of these programs have free versions available. %Gallery-99392%
Roomba's journey shown to be endless, beautiful
We've always suspected our Roomba was actually performing a complex dance loaded with hidden meaning and bewitching charm instead of just bouncing around, and now we've got proof -- check out this long-exposure shot of a Roomba's path over 30 minutes. You can see the initial spiral path in the center, but after that it's a free-for-all that somehow manages to cover the entire room. Now if someone would just make a high-speed video set to the Benny Hill music, we'd be all set.[Via DoobyBrain]
