Calling it 1 trillion FPS is misrepresenting what the thing actually can do.
This camera can take one single picture of bullet going thru an apple. Then you need another apple for the next frame and so on. It only works with light. Which is of course interesting but quite limited when compared with regular high speed cameras.

But, but... The camera captures light, doesn't it? So how can it capture the light which is a ray of active photons at any distance? Should it not reach the camera at all? And thus show as a light beam towards the camera?
I don't get it

#7 In a perfect vacuum you wouldn't be able to detect the beam from the cameras perspective. In this case however, the photons interact with matter and light gets refracted towards the camera. In the air there is not as much matter to send photons off their straight path as in the less transparent bottle. For that reason you can see the ray only very faintly in the air, but at the moment the light interacts with the water the whole scene lights up.
Is this convincing?

Seven years later I'm guessing they can achieve 7 Trillion FPS
