Applying Image effects only for object layer !

Dears,

I'm trying to use the image effect of unity to blur my 3D object and other image effect.
I got a problem that when I want to put it only to the camera focusing on my 3D object unity do it for all cameras !
Please do you know how could I just apply those Image effects only to my 3D objet?

Thank you.

 

I am gonna test what you are saying in Unity 5 and post the results... if I experience this problem and find a solution, I will post it here soon

 

The blurred layer is seen by the camera with blur enabled, depth 0 and clear flags "solid color"
Cube in the front is seen by the camera with depth 1 and clear flags "depth only"

But notice bluriness around the front cube, around it's edges... weird...

BUMP!

 

oh I see Thank you. I will try this tomorrow and back to you!
Hope it works with noise effect and motion blur too. Peace
