This is a nighttime shot of pavement outside St. Luke’s Hospital on Amsterdam Avenue. The light source is ground level, probably from a window on the left, outside the picture frame. The light falls across and illumines the darkened pavement through slats in a wall. I like the patterned serial effect across a horizontal plane. It’s one of these simple things that I must have passed hundreds of times on my walk back and forth from some place or another. For some reason, I noticed it the night I took this photo. I like the different tonalies and textures and find it comforting.
