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.

I approve the use of auto-tuning in these brilliant videos.
Thanks for the link, Angelo!

Steve Jobs Resigned From Apple
Considering that Apple is a company that feeds off of the singular vision of its CEO, I’m very curious to see what the new CEO, Tim Cook, has in store.
Thanks for the head’s up, Tom!
The Physics of Culture
I’m sure that many of you are aware that companies such as Netflix and Amazon run software that tries to predict what movies you like or what your next purchase should be. You may even joke about it or laugh at the suggestions that are proposed. What it comes down to, though, is that there are software algorithms out there trying to describe you. This software is trying to figure out a deterministic formula for you.
Think about that.
Kevin Slavin says:
This isn’t Google. This isn’t information. These aren’t financial stats. This is culture. And what you see here, or what you don’t really see, normally, is that these are the physics of culture. If these algorithms, like the algorithms on Wall Street, crashed one day and went awry, how would we know? What would it look like?
Kevin explains in this wonderful TED Talk how we are writing algorithms that we no longer understand and are unable to predict. In essence, we’ve created another “force of nature".

Great use of technology, timing, and sleight of hand, though I wouldn’t exactly label it as “magic.”

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!
