Two fighters, one referee, and a between-rounds card change all happening at the worst possible moment for anyone trying to follow the actual bout.
Combat sports run on a strict schedule between rounds: reset, instructions, restart. The camera, as usual, found the one beat where the serious business of the fight has to share the frame with everything else going on around the ring. The fighters stayed locked in. The photo had other priorities.
Boxing schedules the breaks to the second: clear the ring, reset, restart on the bell. For one beat the camera has to fit the fight, the corner, and everything ringside into a single frame. The fighters stay locked on the next round. The photo gets distracted.
