Technically Creative- Focal Length

The photo I used to communicate a sense of focal length was taken with a telephoto lens. The telephoto lens takes photos how they are, with no distortion.  The rail gives the photo a sense of depth but I was surprised the plane between the subjects and the back wall seem to blend together.  The purpose of this photo was to create a sort of tunnel to the subjects.  I believe this effect creates a feeling and tone in the composition.  My purpose was to connect the viewer to the subjects.  One could get caught up in the moment of this photo wondering where the thought or view of the subject is. Pride, opportunity, and inspiration all could be themes of this photo depending of the interest of the viewer.  If I would have used a different lens or angel of view in the photo some of the mystery might have been lost.  The leading lines of the railing in the photograph are the most evident element; they bring the eye directly into the picture and lead them to the subject and the thought of this image.  Focal length is a concept and technique that will also help the photographer communicate their intent.
