What I learned from this lesson was that I could adjust the white balance in appropriate situations, where white balance is not required in all places. In addition, this course also I can understand how to play with the color wheel in photography. In this lesson, black and white also played a role in balancing the light, and I learned how to figure out how many steps I needed to modify the settings. For example, I can control light or dark skin color. The zoning system's function then is to arrange various elements in the scene in the zone I desire.
