In Washington D.C., there is a Korean War memorial, which depicts the faces of soldiers on marble. As the viewer looks into the grainy marble, the faces appear in abstract (and thus the grainy texture). As I shot the marble wall, reflections from the surrounding scene seemed to have the soldiers appearing from out of the past to remind us that our freedoms are paid for by sacrifices beyond time.
(The photo is NOT grainy. It is the marble which makes it appear so.)
