Without light, there is no photography. In this course you'll learn about visible light and the electromagnetic spectrum. You will learn about the three most important qualities of light for photographers: brightness, color, and contrast. Then you will learn about how light interacts with matter: how light is absorbed, how light is transmitted, and how light is reflected. We'll demonstrate the three types of reflection: diffuse, direct, and polarized. By the end of this course you will have learned a lot about light, and this will help you to control light, to predict what it's going to do, and to translate your ideas into fantastic-looking images.
