Shutter speed

It seems to be a term that is going out the window with film. This guy is working with a camera that takes a trillion frames a second. It is so fast, the video demonstrates it photographing a pulse of light emitted from a laser, as it travels.

It's a TED video, so I don't know if it will embed, but if not, here's the link.

    I watched that a while back - how they do it went completely over my head. I can't even comprehend being able to understand it

      Yeah, it was on another tread a while ago, seriously cool.

      Because the camera would have to capture the pulse of light, faster than light, which is probably impossible, the camera takes snapshots of the pulse and a computer puts it together.

      It still ends up shooting a pulse of light, but it may not be able to capture true random light patterns like two pulses of light colliding together, but hopefully l am wrong?

        Oops, sorry, guess I'm just not around here enough. That seriously impressed me though. I don't think I've bolded 3 words in all my posts put together up to this topic.
