Shutter Speed and Everything After

1. The shutter speed is fast, because the trucks are in motion. In order to get a clear picture of the trucks in motion, the lens should open for a less amount of time. If the shutter speed was slower, the moving trucks would have been blurry.
2. One rule of composition used in this photo is Leading Lines. There are various lines on the roads and the center barrier that draw our attention to the trucks.
3. Form is a big element of art used in this photo. The three dimensional shapes of the trailers emphasize the shapes of the main subjects in the picture.
4. Movement is a bug principle of design used in the photo. The lines on from the road and center barrier draw the attention of the viewer. The viewer's attention then moves from the lines to the trailers.
