I looked at buying a tilt-shift lens. Ahem. One is not made of money.
So, after a little Googling, I found this tutorial at Photojojo. Incidentally, they have an awesome online store, too. All kinds of good'n'nerdy camera stuff!
Mucking around in the lounge room turned up the following:
|Left side in focus|
|Right side in focus!|
|Whole photo in focus, with a little weird perspective.|
One thing I learned is that less is more. Tilt the lens too far from the camera, and it's just all way out of focus. Plus, I auto-focused prior to unscrewing my lens so that it was reasonably focussed.
Next step - try to make a tilt-shift attachment! Actually, that might be too ambitious :-D
