If you could use super slomotion camera that could see light move, what would you see, sitting in a room when you flipped the light switch off? A washing over of darkness, emanating from the light source- or just sudden darkness?

The photons from the light source that were pointed straight at your camera would end first, so you'd see that go dark. But there's a lot of photons still at play.

The ones bouncing from highly reflective surfaces to the camera would go next.

The rest of the light would be bouncing between less or non reflective surfaces, some of it being absorbed, some bouncing to other places before some of them eventually make their way to the camera.

So you would see the light source go dark, then any mirrors/windows/polished furniture, with the rest of the room steadily dimming with speed proportional to their reflectivity and color.
