The Narrows Bridge and South Perth, digitally tilt-shifted to make it look like a miniaturised model.
On the lower left is the Narrows Bridge over the Swan River, with the Kwinana Freeway snaking its way into the distance on the right hand side.

Note that you should view the large version (by clicking on the image below) to properly appreciate the tilt-shift effect.

Narrows Bridge into South Perth

South Perth, Western Australia
Canon EOS 350D, 17-85mm IS @30mm, 1/400 sec, f/4.5, ISO100

This photo of the Narrows Bridge in South Perth was stitched from 4 photos. AutoStitch (a great freeware application) was used to stitch the photos together.
The tilt-shift effect was simulated digitally, making it look like a miniaturised model.

Tilt-shifting doesn't work for all photos - ideally, the photo should be from a relatively high vantage point, with objects at the same horizontal position in the frame being approximately the same physical distance from the camera.
For more examples of tilt-shift photography, try searching flickr. There's also a tilt-shift miniature fakes flickr group containing many tilt-shift photos.


Edit: I've written a tutorial titled Faking Tilt-Shift - a Tutorial for Realistic Miniaturised Photos, describing how to create tilt-shift fakes.
