I just got Unity 3.1 Pro and I’m trying to implement Depth of Field, but the Depth of Field Image Effect page in the Reference Manual doesn’t match the properties I see when I assign my DoF to the main camera in my scene. Where is the documentation for Image Effects, specifically DoF? Are there any example scenes available?
No example scenes and generally none required as well as the relevant files come with the pro asset bundles and related scripts that for some shaders are required are named according the shader to which they are related 
Whats your specific problem with using it?
(if you want to implement an own one I do not understand the question as the doc etc is about whats offered, not what you might want to do yourself, in that case the shaderlab docs might be more important)
I thought the post-processing Image Effects were more ‘Plug-and-play’ since the scripts come with Unity 3 Pro, and since there is a page describing the properties of this feature. The properties described on the feature’s page (see the link in my original post) don’t match the properties that the script creates. I just don’t understand how to use the script, or any of the associated shaders that come with the script, and I really want to use DoF on a current project.
It turns out, I was importing an Image Effects file from Unity 2 that was left over in the original projects file (created with Unity 2). I’m sorry to have doubted you Unity!
Thanks for your help dreamora! You were right, I didn’t need an example scene, I just needed to pay closer attention.
