Tilt Shift

Tilt Shift is an optical effect or illusion, usually achieved through a digital editing process, whereby a life-size scene is modified to look like a miniature.

The fuzzy parts of the image simulate the shallow depth of field normally encountered in approach photos or macros, making the scene look much smaller than it actually is. The blur effect can be achieved optically, when taking the image, or by a subsequent digital processing. Many photos that produce this effect are drawn from high altitude to simulate the effect of looking at a model from above.
