Light Theory

When I first started drawing, one of my favorite fundamental based YouTube channels was Proko. He breaks down more complex techniques of drawing into understandable, bite-sized chunks. This video deals with light theory, which is different than color theory. In reality, all visuals that we see are simply light interacting with 3D objects. Proko does a fantastic job taking this simple realization to show how light interaction can be used to bring out form in drawing.
