This document discusses various lighting techniques used in 3D graphics and Unity, including physically based rendering, light probes, subsurface scattering, pre-integrated skin shading, color grading, reflection probes, indirect lighting, cubemapping, image based lighting, high dynamic range, conservation of energy, and global illumination. It provides examples of lighting in games and images to illustrate different techniques.
