A pair of shoes, dangling from a power line. This line sweeps down across the road rather than being level. I thought the shoes made a nice silhouette, though I wasn’t considering that at the time. The blue sky is quite visible in the original. In Adobe Camera Raw, I pushed the contrast slider all the way to the right, which made the image look like this. I didn’t have to white out the background at all, since it was the brightest part.
