Tilt Shift

Tilt Shift is a specialized version of the Depth of Field effect that allows for very smooth transitions between focused and defocused areas. It is is easier to use and is generally less prone to unsightly image artifacts. However, since it relies on dependent texture lookups, it can also have a higher processing overhead.

As with the other image effects, this effect is only available in Unity Pro and you must have the Pro Standard Assets installed before it becomes available.

Properties

Focal Settings
Visualize	Visualizes the focal plane in the game view with a green tint (useful for learning or debugging).
Distance	The distance to the focal plane from the camera position in world space units.
Smoothness	The smoothness when transitioning from out-of-focus to in-focus areas.

Background Blur
Downsample	Downsamples most internal buffers (this makes the effect faster but more blurry).
Iterations	Number of iterations for blurring the background areas (ie, everything behind the focal plane). Each iteration requires processing time.
Max Blur spread	The maximum blur distance for the defocused areas. Makes out-of-focus areas increasingly blurred.

Foreground Blur
Enable	Enables foreground blurring. This typically gives a better result but with a cost in processing time.
Iterations	Number of iterations for blurring the foreground areas (ie, everything in front of the focal area). Each iteration requires processing time.

Hardware support

This effect requires a graphics card with pixel shaders (3.0) or OpenGL ES 2.0. Additionally, depth texture support is required. PC: NVIDIA cards since 2004 (GeForce 6), AMD cards since 2005 (Radeon X1300), Intel cards since 2006 (GMA X3000); Mobile: OpenGL ES 2.0 with depth texture support; Consoles: Xbox 360, PS3.

All image effects automatically disable themselves when they can not run on end-users graphics card.
