'Tilt Shift' photos are something that has fascinated me for a while now but they're something I'd never have the time to look into creating from scratch. It's a lot more technical than this, but in short it an effect which can make people / objects / landscapes etc in photos all look miniture, - like a little toy town if you like. Try Googling for examples or looking round Flickr.
Normally it's quite a lengthy process which also involves a decent spec camera for a start. However I came across a link to this site a few months ago; tiltshiftmaker.com/
Which allows you to have a go at it with your own photos in 3 easy steps.

This is example is no where near as effective as some of the ones kicking around the web but I was pleased for how long it took.
If you really want to be impressed check out this example of a Tilt Shift video;

You constantly have to remind yourself that the video isn't just a load of toy people!
