Shutter Speed

The first picture is without someone running Ito the picture, whereas the second picture shows someone running into it. The reason why I caught him mid running is because I used a fast shutter speed to capture him still. 

In this picture there are several uses of triangles, this keeps the viewers inside the picture. The first thing the viewer sees is the runner inside the picture, especially towards his leg because a direct triangle is formed.

This picture connotes to me some sort of race is going on because the photographer here captured someone moving fastly.
