CGMA - Color and light

I have started on my second class at cgma. This time it is color and light with Ryan Lang and Tyler Carter. First week's assignmet: three balls with neutral local colors, not warm or cold; that is, red, blue and yellow, in diffrent lighting situations: neutral key, warm key and cold key. A good point I got with this week's assignmet: the absens of one lightsource usually means the presence of another. In full daylight, the sun would be the key light and the sky light would be the secondary light source or the fill light. In natural lit outdoor enviroments, this would normally be the case, one major key and a fill light. In the absence of key and fill, is where ambient occlusion or contact shadows appear. In the contact point between the balls and the ground, light is being occluded since light loses its energy bouncing and doesn't have the strenght to reach in the crevasses. In an outdoor lit scene, the sun/key light would usually be warm and the shadows cold. A good rule of thumb is: warm light- cold shadows and cold light - warm shadows. 


I have tried to apply the principals learned, in my daily work on Light Apprentice chapter 2.
