This was made with a DSLR and a swinging lens to provide selective focus on the milepost at left. This moved the plane of focus to be non-parallel with the sensor, yielding only a sliver in focus.

Image was was captured at “Park Junction” in Philadelphia, where the former Reading Railroad once met the former Baltimore and Ohio Railroad. What caught my eye was the old school graffiti moniker on the base of the milepost, in a style traditionally used by yard workers and hobos to tag freight cars.
