If you’ve browsed Flickr for city photos for any length of time, you have probably come across photos which have had a tilt-shift effect added to them. A tilt-shift effect basically results in the photo looking like a model, and Mathieu ‘p01′ Henri has created a canvas demo that creates this effect.

A blurred version of the original image is generated using Canvas and drawImage(), then horizontal slices are composited with the original image to produce the final output. The blurred image is generated incrementally to improve the quality of the blurring effect. Without this, it would feature heavy bilinear interpolation approximations.
