- Hi, I'm Chris Meyer of Crish Design. And welcome to the After Effects Apprentice lesson on creating transparency. One of the keys to creating interesting composites on multiple images is to cut out portions of images, either to draw the viewer's attention to a particular feature of that image, or to reveal other imagery behind. Your main tool for doing this is called masking. Masking allows you to draw outlined shapes. Either using a pen tool, or certain parametric shapes like circles and rectangles, to go ahead and reveal portions of an image. Once you've done that, you can animate that shape, add multiple shapes, or apply affects that either fill in portions of that shape, or draw an outline around that shape.
In addition to using masking, you can also use Stencils and Track Mattes. These use properties of other layers, such as their alpha channel, or their greyscale values, to either obscure or reveal portions of one or multiple layers underneath. We're going to demonstrate using all these techniques, and show you a few tricks along the way. Hope you have some fun. Let's dive in.
