As I was preparing for an upcoming workshop on PowerPoint, I wanted to show people how to make thier own custom background using the Slide Master. What I wanted to do was show them how to take an image an make it semi transparent so I could use it as a watermark. In the past I would just do this in Photoshop, but many in my audience do not have access to Photoshop, and plus I wanted to keep this workshop strickly PowerPoint oriented. Since I can do many things with an image in PowerPoint now, I figured making it transparent should be a breeze, but as I soon found out there is not. Well there is a way, but it is a very easy cheat and it is as symple as inserting a shape box (retangle box).
The cheat: Well after some playing around I found a way. It was quite simple actually and I also could add a blur and adjust it so it would make the perfect watermark. Check out the tutorial video here.
