Adjust the brightness, sharpness, or contrast
Click the picture that you want to change the brightness for.
On the Picture Format tab, in the Adjust group, select Corrections.
Depending on your screen size, the Corrections button may appear different.
If you do not see the Picture Format tab, make sure that you have selected a picture. You may have to double-click the picture to select it and cause the tab to appear.
Do one or more of the following:
Under Sharpen/Soften, click the thumbnail that you want. Thumbnails on the left show more softness, and more sharpness on the right.
Under Brightness/Contrast, click the thumbnail that you want. Thumbnails on the left show less brightness, and are brighter on the right. Thumbnails on the top show less contrast, and more contrast on the bottom.
Tip: When you point at an option in the Corrections gallery with your mouse, the picture on your slide changes to give you a preview of the effect of the option you're pointing at.
To fine tune any correction, click Picture Corrections Options, and then move the slider for Sharpness, Brightness, or Contrast, or enter a number in the box next to the slider.
Note: If you are using PowerPoint, you can still save the original version of the picture, even if you have made corrections. This feature is not available in Word or Excel.
