This is incredible. Watching the duality of light in super duper slow motion! Awesome! Science rules!
In 1964 MIT professor Harold Edgerton, pioneer of stop-action photography, famously took a photo of a bullet piercing an apple using exposures as short as a few nanoseconds. Inspired by his work, Ramesh Raskar and his team set out to create a camera that could capture not just a bullet (traveling at 850 meters per second) but light itself (nearly 300 million meters per second).
Stop a moment to take that in: photographing light as it moves. For that, they built a camera and software that can visualize pictures as if they are recorded at 1 trillion frames per second. The same photon-imaging technology can also be used to create a camera that can peer “around” corners , by exploiting specific properties of the photons when they bounce off surfaces and objects.
Among the other projects that Raskar is leading, with the MIT Media Lab’s Camera Culture research group, are low-cost eye care devices, a next generation CAT-Scan machine and human-computer interaction systems.

“Though photographs in the near future will still be composed by people holding cameras, it will gradually become more accurate to say pictures were computed rather than ‘taken’ or ‘captured.’”Popular Photography magazine
Photographer Michael Chrisman used a pinhole camera fitted with photosensitive paper to make a 365-day exposure of the Toronto skyline from Jan. 1, 2011, to Dec. 31, 2011.
A lovely year-long exposure of the Toronto Skyline made with a pinhole camera. Over 365 different streaks of the sun as they slowly pass the sky creating the streaks.
I’ve TRIED to make a pinhole camera myself and it is not easy – this is super impressive.
The camera, a simple black box, was mounted to the side of a rusty metal box next to a shipping beacon near the shipping canal. Chrisman used tape and a few bricks to “secure and position the camera for its long wait,” he said in an email exchange with the Star.
Chrisman, a 31-year-old freelance editorial and art photographer, put it there on Jan. 1, 2011, knowing a lot could go wrong. Mishaps could include the camera being stolen, which has happened in some of his earlier time-exposure experiments.
I saw this in Wal-Mart today and I really want to get it. Looking to get it online at Amazon. Excitedddd. It’s pretty sweet and ultra nerdy. A’la me.
Amid all the ceremonies and what not about this day 10 years ago, I am going to post this one picture. To be honest, September 11th didn’t mean a lot to me. I was only 11 at the time and I had no idea of the implications of it for the future. I remember my grade 6 teacher pulling in the TV so we could watch it during class. But the weight of the situation didn’t hit until I was much older. This is going to be the defining moment of our generation, as the generations before us had World Wars and nuclear bombs.
