photo finish

Knight's Choice has won Australia's famous Melbourne Cup, in a dramatically close race which went to a photo finish.

The race is where it seemed to be headed at the beginning of the year – a photo finish where either candidate could end up on top.

Since then, Harris’s campaign has had ups and downs, and is now locked in what is shaping up to be a photo finish next week.

He beat Jamaica's Kishane Thompson in a dramatic photo finish to edge what has been described as the fastest 100m race in history - with the slowest of the eight finalists clocking an impressive 9.91 seconds.

The photo finish process begins with three cameras — main, backup and infield — aimed at the track from different angles.
