Action Shots

1. The way the action was frozen perfectly and how it was taken before the oath started reacting makes this picture a great photo and illustrates the surprise of the action.
2. The shutter speed would have to be high to freeze the movement of the water.
3. This is a key moment. Yes, this could have been planned, but it is not probable. 
4. The framing and the ability to avoid getting water on the camera are advanced in this photo.
