Tilt-Shift Van Gogh
The visually stunning field of tilt-shift photography became a fairly big thing in the Web a couple of years ago. It uses a special lens that gives a real-world scene the illusion of being a miniature model ... the effect can be simulated in Photoshop, by adjusting a photograph's contrast, colour saturation and depth of focus. It works quite well with regular photographs ... and it turns out that the works of Vincent van Gogh ... make excellent subjects for this kind of treatment.
