In this photo I see CONTRAST within the water. The water starts off really dark at the bottom of the picture but its gets lighter as you look up the picture. As well as UNITY because of the contrast in the water the line in the coloumns value on the railing and shape from the circles within the water. They all go together to form UNITY
This image shows VALUE. Because of the darker left side of the theatre slowly getting brighter as you move to the right.
