Tilt-Shift Photography: This category was created to display photos that have been converted to a Tilt-shift picture. "Tilt-shift photography" refers to the term is used when the shallow depth of field is simulated with digital post-processing, as will be the case for the photos shown here.
the use of camera movements on small and medium-format cameras, and sometimes specifically refers to the use of tilt for selective focus, often for simulating a miniature scene. The name may also derive from a tilt-shift lens which is normally required when the effect is produced optically. "Tilt-shift" actually encompasses two different types of movements: rotation of the lens plane relative to the image plane, called tilt, and movement of the lens parallel to the image plane, called shift. Tilt is used to control the orientation of the plane of focus (PoF), and hence the part of an image that appears sharp; it makes use of the Scheimpflug principle. Shift is used to adjust the position of the subject in the image area without moving the camera back; this is often helpful in avoiding the convergence of parallel lines, as when photographing tall buildings.

I generally use http://tiltshiftmaker.com/, an online site that converts photos, up to a certain size, for free. The most common use for Tilt-Shift is miniature faking; a creative technique whereby a photograph of a life-size location or object is manipulated to give an optical illusion of a photograph of a miniature scale model. Altering the focus of the photo simulates the shallow depth of field normally encountered with macro lenses, making the scene seem much smaller than it actually is. In addition to focus manipulation, the tilt-shift photography effect is improved by increasing color saturation and contrast, to simulate the bright paint often found on scale models. Most faked tilt-shift photographs are taken from a high angle to further simulate the effect of looking down on a miniature. The technique is particularly effective on buildings, cars, trains and people.
