Describing the Fresnel effect

Another important concept to understand when talking about reflections is the concept of Fresnel reflections. Fresnel reflections are named after the 19th Century French physicists Augustin-Jean Fresnel. This property describes how reflections behave based on the angle at which they are viewed. The angle which the surface is viewed is often referred to as the angle of incidence. As a surface turns away from the eye or the rendering camera, it can become increasingly reflective.

So a good example of this is this render that I have right now. I'm comparing two different surfaces. They have an equal amount of reflectivity applied. But this surface exhibits the phenomena of Fresnel reflections. You can see on the parts of the surface that are more perpendicular to the camera are less reflective than the parts of the surface that are moving away from the camera. You can sort of think of it this way. Pretend that you are standing at the edge of a clear lake. If you look straight down into the ...
