In Photoshop, the layers are combined to create the final image. A variety of layering options are used to
achieve the desired effect. For example, shadow and occlusion passes are often layered on top of base color

passes.
Next, the text boxes, dialogue, and other effects such as atmosphere and lighting are layered in. When
the desired integration of all the elements is achieved, the final image is flattened and ready to be rolled into
