Is it possible to add camera effects to Unity Camera?

I was wondering if it is possible to add effects to the default camera. I have a 2.5D game with the camera following the character. I want to know if there is any way to add something such as film grain or static to the camera. If this is completely obvious then I apologize:)

Yes, this is completely obvious to anyone who has read the manual.

Of course, if you don’t have Unity Pro, then the answer is of course no.
