So today is the day the new Brad Pitt movie World War Z opens and in this tutorial I just had to play around with some of the destruction seen in the various posters promoting the movie. I also wanted to show you how you can add a simple free 3D model of a helicopter can be added and how you can control the angle and lighting to get the composition just right without having to live with whatever angle it would otherwise be in a stock photo. This is just one of the many advantages in creating composites with 3D in Photoshop. Also below I have provided the custom brushed I used to create the smoke, debris, and fire effects so you can try it yourself. Be creative and have fun!
