The Beginning of the Line

28 March 2010. Philadelphia, PA. At Milepost 0 (QA-0, technically) of the CSX Railroad's Trenton Line, near Fairmount Park, Philadelphia. The location is known by the railroad as "Park Junction". I really like this location.

The very selective focus here was achieved by tilting the lens. Normally, the plane of focus is parallel to the camera across the frame. Eg. if you focus 10 feet away, the sharpest focus is 10 feet away across every part of the frame.

But by tilting the lens relative to the sensor, the plane of focus becomes *diagonal* to the sensor plane. Here, this was used to put only one object (the mile marker on the left) in focus.

More commonly, tilting the lens is used to allow *more* objects to be in focus. For example, a landscape photographer photographing a deep field of flowers might tilt the lens downward, keeping flowers on the ground in focus from close to the camera into the distance. But it can also be use to force parts of the frame that would otherwise be in focus to become soft and dream-like.

... Using tilt for selective focus (or artificially defocusing large parts of the frame with a photo editing program) can, for some subjects, create an illusion that a full size subject is actually a miniature model. The effect isn't fully understood, but it generally requires a high perspective and using selective focus to mimic the very thin depth of field characteristically found in macro photography.
