Park Junction, Philadelphia, PA, 2010.More pixels than are warranted at flickr.com/photos/mattblaze/44#photography

A single railroad track, receding into the distance, in a lonely urban area behind some houses. Almost everything is in soft focus. A railroad milepost, marked "O QA" is in sharp focus at left. There's a hobo-style graffiti tag on the milepost.

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.

    @mattblaze Is that some kind of panorama lens? Such an interesting technique!

    @LillyHerself Tilt and Swing movements (which are possible with large format view cameras and as a feature on a handful of specialized DSLR lenses) tilt the plane of focus away from the film plane. Usually, the same distance from the camera is in focus across the frame. With tilt and swing, the focal distance changes across the frame. This can be used to keep, e.g., the ground in focus in a landscape as it goes to the distance, or, as here, to restrict what's in focus to a narrow slice.

    @mattblaze @LillyHerself I think this is the technique used to create the sensation that you're looking at a model train sized scene when it's actually human sized. (Matt, you know this stuff far better than I do, so please confirm or correct)

    @mweiss @LillyHerself Yes, indeed. (Though a lot of people simulate it in a photo editing program). To get the simulated miniature effect, you generally shoot from a high vantage point and selectively focus on a a horizontal stripe across the frame.
