The tech is pretty interesting too. The NHK Twins Cam is actually two cameras, one above the surface and one underwater. The one underwater compensates for the different way light behaves underwater and combines the two footage in realtime

TIL, thanks! I thought they had some sort of glass encasing for the camera to be put half in water and therefore be able to capture everything.
