In The Spotlight - How to Create a Spotlight Effect in PowerPoint

In PowerPoint, you can simulate the appearance of a spotlight shining on your Clip Art by drawing a circle and setting it to semitransparent. For this to work, the scene must be flat.

1.                  Insert your Clip Art

2.                  Use the Oval tool from the PowerPoint Draw menu to draw a circle

3.                 To draw a perfect circle, hold down Shift while you use the mouse to make the circle.

4.                  Now size the circle and move it over the Clip Art

5.                  Make sure that it's over a flat scene--for example, on one wall of a building.

6.                  With the circle selected, click on the arrow to the right of the Fill button (the Fill button shows a bucket of paint)

7.                  When the list expands, select white

8.                  Right-click on the circle now, and choose Format AutoShape

9.                  When the dialog box opens, select the check box labeled Semitransparent and click on OK.
