High Speed Video of Canon DSLR Shutter
Here’s a great video showing the mirror and shutter mechanism in a Canon DSLR. The action begins 60 seconds in.
Keep in mind that the entire real-time duration of the mirror swinging up, the shutter coming down, the exposure, the shutter coming back up and the mirror swinging down is .213 seconds.
Great find, Tom!
Google Store View
My favorite camera store, B&H Photo Video, is one of the first businesses participating in having virtual tours of their stores via Google’s Street View technology.
If you look up B&H Photo Video on Google Maps, you can step inside.

Capturing video at the speed of light — one trillion frames per second
So what kind of camera do you have? How fast can it shoot? 1/4000th of a second? 1/8000th of a second? Pshaw. What do you think of a camera that can shoot 1/1,000,000,000,000th of a second? That’s so fast that it can capture light traveling in slow motion!
MIT researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That’s fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle’s bottom.

Photography Themed Rube Goldberg
I’m a sucker for elaborate contraptions—especially ones that involve themes that are near and dear to my heart.
Enjoy!
Leica Lenses Sliced in Half For Science!
Pictured above is a Leica Tri-Elmar-M 28-35-50mm lens cut neatly in half. Call it death of a lens. I call it an interesting display on the intricate mechanical workings of a camera lens.
These were actually made by Leica students as a graduation project and boxed as a “cutaway model” of the lens.
This also gives you a good mental image of what you can potentially break if/when you drop your lens.
Thanks for the link, David!

Light Field Photography with a Plenoptic Camera
I’ve been keeping my eye on plenoptic lenses since I saw this Stanford Research paper on the topic back in 2005. In layman’s terms: with a Plenoptic Camera, you’ll never take an out-of-focus image again. Using a special lens composed of an array of micro-lenses, more information is captured than your usual camera setup (see image below from Laptop Magazine):
Special software takes the above image and resolves it into a traditional photo. The kicker is, though, the user can choose where the focal point is during this post-processing step. It’s pretty amazing and will revolutionize photography as we know it. Here’s a video demo:

Bound for Glory: America in Color
This is an amazing collection of color photographs taken during the Great Depression prior to World War II.
From The Denver Post:
These images, by photographers of the Farm Security Administration/Office of War Information, are some of the only color photographs taken of the effects of the Depression on America’s rural and small town populations. The photographs are the property of the Library of Congress and were included in a 2006 exhibit Bound for Glory: America in Color.
Great find, James!

Strip Camera Photography
A co-worker pointed showed me an interesting abstract sports photo using a technique called “strip photography.” Naturally, I did the smart thing and did a search for “strip photos” in Google. Then I quickly closed that tab and did a search for “strip photography” and found a great article on this interesting art.
This diagram sums it up nicely:
The concept is simple enough, but the results are breathtaking. Thanks for the tip, Tim!

Afghanistan School for Girls
In Afghanistan from 2006 to 2008, there were 461 attacks on schools for girls, and in 2008, 15 girls were attacked with battery acid on their way to school.

Koba, 22, has been teaching for two years. She was the only teacher who allowed the photographer to take her picture. (Other teachers feared reprisal if their families found out they’d been photographed.)
