Lambert's Cosine Law is such a simple yet integral part to the accurate portrayal of how light interacts with surfaces. It subsequently enhances the realism and immersion of digital scenes. This slide is nice because I can visualize how it works.

I heard about the cosine effect works in a similar fashion with how you view the surface from a certain angle. The viewing angle won't affect the total brightness you see because when you view a surface from an angle you see the reflected light is proportional to cosine and the surface area is proportional to cosine.
