The free "Projection Screen" actions create static and animated projection screen that display your photos. The second action of the set creates a 60-seconds slideshow using 10 photos of your preference. Some of you may want to create a custom slideshow with more, or less photos. This tutorial will show you how to use the set's first (static) action to create an animation, which commences with the screen rolling down softly from the projector tube; the room lights dim and the projector displays your photos, while its light beam flashes. At the end, the room lights are switched on, and the screen retracts into the tube again!
If you are not familiar with the basic concepts and tools about Photoshop timeline animations, I recommend you watch the "Photoshop 2D animations explained" tutorial first. In this tutorial you will learn some more advanced techniques (e.g. how to create video groups, how to use and customize transitions, etc).
