At the end of a long day, we wanted to do some commercials with Katja with the double tank and her twin-hose regulator. We had rented the pool for the evening to another photographer. Therefore, it was not at all right when Katja lay flat on the floor of the pool and paused for her own pleasure. "Who knows when I can have that feeling the next time," she apologized later. We forgave her. Anyone who watches this clip will understand.
