Light EQ™ in Edit mode works like a sound equalizer, but with light. You can adjust the brightness and contrast of different tone bands (areas of relative brightness or darkness) independently using a slider for each tone band. A graph shows the amount of brightening or darkening applied throughout the tonal range of your image. The gradient on each slider indicates a tone band, which you may choose to darken or lighten by moving it up or down. However, before doctoring on a finer level, you can simply press the Auto button. Light EQ™ technology automatically analyzes the image and lightens or darkens accordingly, taking out all of the heavy lifting. After, only a few minor tweaks, if any, are necessary.
