Adjusting Photo Contrast and Brightness

PowerPoint is not a very sophisticated photo editor, but it can do some very elementary things like increase or decrease a picture's brightness and contrast. The easiest way to access those controls is through the Brightness and Contrast drop-down lists on the Format tab. For example, Figure 13.11 shows the Brightness settings. To choose a value other than the ones listed, click Picture Corrections Options to open the Format Picture dialog box, also shown in Figure 13.11. From there you can enter an exact percentage or drag the Brightness and/or Contrast sliders.
