How to cut out shapes out of images in PowerPoint
PowerPoint can do Photoshop-like tricks. One of them: cutting shapes out of images. Here is how to do it:
Drag your image on the slide
Draw a shape on top of it (the freehand shape allows you to create a very precise shape)
First select the image, then select the shape (shift click)
Now select the Shape Format menu
Click Merge Shapes
Click Subtract
That's it. Below is a slide from the template store that uses this technique (you can download the ready-made slide if you want)
