As I go through some of my old presentations and start to update the graphics, I had a 2 slides of Book covers, the first was a real book cover and the second was a revision of the first. What I did originally was went to a website and grabbed the book cover, but like most book images on the web this image was just of the cover, and was flat. So in my update I created a 2D looking book image by creating a template in Photoshop (Click here to download the template). This surprisinlgy is pretty easy to use, you just need to use Photoshop template provided, the Transform tool and learn how to use Distort option. As I create images for my presentations, I sometimes like to make my own fake book covers to make a point, as I show in the tutorial I reference a fake Visual Broccoli for Dummies book mock up. This mock up like most images I use in PowerPoint simply becomes my "bullet" point of what I want to talk about. Check out the tutorial and try it out. In the template provided you have layers that add some realistic looking qualities like shadows, highlights and as a bonus I show you how to add a slight page curl to the cover.
Check out the tutorial and let me know what you think.
