I made these two images to show the effects of changing the Fog Bias setting (top image) and the Fresnel Reflections setting (bottom image).
The 2 Back Rows have a Diffuse color of 0,0,0. The Back Row has a Reflect color of 220,135,0. The Left most column does not have the Fresnel reflections box checked. The most right pawn in the back row has a Reflection Glossiness of 0.5. All others have a value of 0.8. Feel free to download these two images if you find them useful.
