Ok, I'm trying to do this fresne node thing on a floor to get a reflection instead of doing the reflection/refraction like I've always done.  Only the above screenshot is what I get. 

I'm using a black and white floor tile, but after applying the fresnel node, the floor becomes completely black without any shine.  I have looked at the tutorial at RDNA but I'm still confused :( 

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
