Shadows and silhouettes can do so much for a photograph. They can provide depth; they can help to focus the attention of the viewer; they can provide dramatic subject matters. They can also make for complex photos; ones that force the viewer to take a little extra time to process what they’re seeing.
Stephen’s photo above is such a complex shot. With the predominant color of the photo being this featureless black, it forces the viewer to seek out clear details in order to understand what they are looking at. And once the viewer sees the corner of the sign on the left side of the image, the photo unfolds in the mind’s eye: an underground Metro platform; the black blobs take shape as people; and the blurred gray becomes an incoming train. The central focus of the photo, the sharply defined silhouetted commuter, suddenly stands out and you wonder how you didn’t see it immediately. This is excellent work!
