Super fast exposure time - BBC News
« on: August 02, 2013, 06:52:54 AM »
"Scientists in the US have built a camera that can show light moving by taking pictures with an exposure time one billion times shorter than a normal camera.

The device, built at the Massachusetts Institute of Technology, can take an image every two picoseconds."

That's pretty damn cool! Especially the part about the taking a photo of something that's not in your line of sight! Crazy stuff.

Does it use dual DIGIC6+ chips?

Can I get it in a 5d body for less than $4000?

Is this what the upcoming Canon announcement is for??

Cool technology, but to light the scene, you'd need a constant light that would blind the eyes.

Pretty sure you can use any light, since its quite literally capturing a photo of light. You just adjust the exposure to compensate for the amount of light like we already do.

Right, so at 1 billionth of the current max shutter speed of 1/8000 s, to 'just adjust the exposure to compensate for the amount of light like we already do,' you'd need to go 36 stops higher than ISO 100.  Know any cameras that can set ISO 6,871,947,673,600?   ::)

WOW!

It looks strange they're using a old Sigma 28-70/2,8 instead of a superfast lens, considering they need multiple exposures to get the image at that crazy fast frame rate.
Thanks to the new Sigma service, I could borrow them my Canon 50/0,95...

Yes, I think this video was made around 2010-11. So MKII should be out within next year...

I am unimpressed with the DR of the around-the-corner shot...

I think the BBC report was using that as an example. I'd be they are using their own custom optics for this. Probably. I could be wrong though.
