Is it actually taking 2 million pictures per second, does the title just mean that the global exposure takes 1/2000000 of a second?

Really cool results, although that bullet catcher setup is slightly horrifying.

Yep, that's the exposure time.

LOL, yeah, it looks pretty sketchy. It is a proper bullet trap though, in fact the very same one that Harold Edgerton used for his famous bullet through apple image :)
