For people/handler emotion, start shots are good: and for dog excitement, finish shots with the dog hitting the motivator for a reward-game. Fastest dog in the USA (and world) is named Moose, runs for Spring Loaded I think, not sure where they are based. That is a broad hint for posting a shot here if he happens to be running.
Also people-wise, box-loaders work fast and smart to get a new ball in for each dog (correct size and on its correct side of the box), and call each dog to give it the direction to start a run, so are worth a few shots of themselves with a dog turning (as distinct from cut off at the knees to show just the dog).

Judge says "Teams ready, watch the lights" Start-dogs are released at the green light.
Also find many owners appreciate a portrait, they generally have some action shots of their dog but not a good head shot.
