One of the most impressive buildings I saw on our quick tour through the streets of Leiden had a number of niches built into its façade. The sun was bouncing off a nearby canal and reflecting patterns of light into this particular niche. Incredibly, the reflected pattern of sunlight here repeated the X shape of the sails on the sculpted windmill in front of this niche. I photographed it several times in color, which emphasized the brown bricks and the tan niche. Those colors competed with the coincidental match of the reflected light pattern and the windmill. When I converted it to black and white, the image comes directly to the point – the repetition of those X’s.
