In the final composition form of the frame, we see how virtual lights offer illumination from countless sources of light including neon signs, street lamps, and headlights. The reflectivity of the cars' bodies and the wet streets need Raytracing, a computation-heavy technique. As well, other visual details including colored fog around signs and lens flare from headlights have been added. Finally, the finished rendered image is processed at Pixar's Renderfarm and must be seen to be free of any visual artifacts.
