A photograph Fred Ressler (b. 1941) snapped in 1995 revealed a portrait filtering through foliage, against the side of his home. For the next five years, Mr. Ressler would wander through his wooded property in search of images entwined in the shadows. The play of light revealed proportionate visages. The number of features that are recognizable in shape, size and placement is decisive for Mr. Ressler. Each image must have at least four discernable features, such as a head, nose, chin, and eye. The maximum number of harmonious features he had realized in one photograph is 36, in an image of Albert Einstein.
