This photo is of a competitor passing uniformed judges during a three-day event competition at the 1928 Olympic Games in Amsterdam, Netherlands. Formidable looking jump judges such as these would inspire me to make great speed to the next jump! But jump judging hasn't changed greatly, as it still requires a person to decide if the horse has cleared the jump without behavior that would incur penalty.

Does one gentleman hold a stop watch in his hand? Like in any timed sport, timing equipment has become more accurate and riders wear digital watches with large readouts so they can stay within the 'optimum time'.
