Photoshop images appear on flat screens, but they are actually three-dimensional because of the power of layers. In the virtual world of the Photoshop work flow, layers are the third dimension. Beyond the height and width, they create depth.
Layers are critical to working dynamically in Photoshop. Fragments of an image saved on individual layers can be edited separately and moved independently of each other. The stacking order of layers can help determine the depth and position of visual elements within the picture plane. In short, working with layers gives you tremendous control over the image during the process of creating it.
