A while back I wrote about cool style of photography, called tilt shift, that makes aerial photographs of real scenes look like miniature models. The effect is charming, but expensive, because you have to buy a tilt-shift lens.
Here's a nice little tutorial for faking the same effect using Photoshop. The results are very nice.

While purchasing a "real" tilt-shift (as you were calling it, in my business we call it a "swing and tilt") is too expensive for most of us, there is a cheap alternative. For about $100 you can get a Lensbaby, which is a super analog lens. No focus marks, manual apeture (I mean real manual.) I've been shooting with one for over a year and it is easily my favorite single lens (particularly on the bang/buck ratio.)
