Tilt Shift Effect

This is a photograph of a real fair that has been strategically blurred to give the effect of a model fair.

A Photoshop Instruction Summary:

~Copy your image and group the copy to a levels layer

~Apply a Gaussian Blur to your top image.

~Use a black to white Reflected Gradient on the levels layer to un-blur a portion of your image.  Drawing straight up works best  (hold shift as you draw).

~Add a new levels layer on top and group it to the image copy.  Play with brightness and contrast to give the blurred colours a boost.
