Replying to Could you see light moving with a Phantom Camera?

Unless I F'd up my calculations really bad, with a phantom Camera shooting at 1,000,000 FPS you could slow video down 4.16e4 times(1e7/24fps). The speed of light is 3e8 so in turn you could slow it down to be traveling at a relative 7200 m/s. This is still really fucken fast but if you filmed a light being turned on in a really large room you could see frames where the light filled only parts of the room.
