Modifying Picture Brightness and Contrast


PP07S-3.4.2

Once you have inserted a picture, you can control the image's colors, brightness, and contrast using Picture tools. The brightness and contrast controls let you make simple adjustments to the tonal range of a picture. The brightness and contrast controls change a picture by an overall lightening or darkening of the image pixels. You can experiment with the settings to get the look you want. If you don't like the look, you can use the Reset Picture button to return the picture back to its original starting point.

Change Brightness

Click the Format tab under Picture Tools.

Click the Brightness button, and then do one of the following:

  • Click a positive brightness to lighten the object colors by adding more white, or click a negative brightness to darken the object colors by adding more black.

  • Click Picture Corrections Options to set other specific brightness percentages.

Change Contrast


Click the picture whose contrast you want to increase or decrease.

Click the Format tab under Picture Tools.

Click the Contrast button, and then do one of the following:

  • Click a positive contrast to increase color intensity, resulting in less gray, or click a negative contrast to decrease color intensity, resulting in more gray.
