How PowerPoint adds a special effect to a picture
After you create a new slide in PowerPoint 2016, switch to the Insert tab, and then click Picture to import a picture that requires a special effect. You can also copy a picture file directly in a Web page or explorer, and then press CTRL + V in PowerPoint to paste directly.
When the photo is selected, switch to the Picture Tools-Format tab, and then click on the "picture effect → three-dimensional rotation → perspective" to select the "left contrast" effect.
Now the picture has a perspective change, but it's not cool enough. Continue to select the picture, and then click "picture effect → image → image variant", choose a reflection effect.
At this point the effect is good, but not strong enough, we need to set a background to the backdrop, you can try the gray background. Right-click the slide select Set background format, select Solid fill in the right pane, and click the Color button below to select a gray. At this point, a very cool picture effect is displayed. Of course, we can also add more embellishment, such as adding the corresponding text, and so on, the effect will be better.
