Choose five different scenes and shoot each scene at three different exposure settings, one stop overexposed, exposed at 18% gray (middle), and one stop underexposed.
Compositional Focus: Choose scenes that have fairly even tones. A scene that is overly bright or overly dark will be more difficult to use the first time you are doing this.
