Tilt-shifting is a photographic technique that creates images with very narrow depth of field. It can be used to take real images and make them look like photographs of
miniatures. The site
tiltshiftmaker.com creates the effect for you. It works best with images with lots of detail on the foreground: houses, cars, people. An example from the tiltshiftmaker site, a town on the Amalfi coast in Italy.
