Chapter Five, "Type and Shape Layers," are two kinds of layers that have not been covered as yet. While type layers are what you use to add text to a Photoshop document, they have a lot more power available to them as well. With type layers you can let your text take on a life of its own. Shape layers allow you to work with shape in your documents. Here you will work to making a poster using the Shape tools. With these, you can go beyond the simple shapes and create complex one.
Chapter Six, "Enhancing Photos with Layers," is about how to enhance digital photos by the use of layers. Here you will learn how to combine multiple layers, paint with light, perform selective sharpening, dodge and burn, create a pseudo HDR look, replace a sky, auto-align for group exposures, enhance depth of field, and create soft focus.
Chapter Seven, "Retouching with Layers," is not a be-all, end-all stop for retouching, but there are a number of things that you can do to retouch photos within Photoshop. Here you will learn how to use some of the previously learned techniques to retouch photos as well as some techniques that have layer related options. These include removing wrinkles, smoothing skin, whitening eyes and teeth, removing distractions, and the use of content aware fill.
Chapter Eight, "Layer Styles," are really layer effects that are contained within Photoshop. These are things like shadows, bevels, glows, and strokes that can be applied to any layer. What's better is that layer styles can always be edited, and they can be saved so that you can apply that effect to another image.
Chapter Nine, "Smart Layers," discusses the fact that in CS3 and CS4, Adobe started making it possible for layers to be indestructible. That is, these layers allow you to do things to layers in a non destructive manor, and, in CS5, you can even apply a filter to a layer and still go back and change the filter settings at any time.
Chapter Ten, "Advanced Layer Blending and Compositing," is the one new chapter in the book. This one has four more tutorials — as well as one that was moved from the Blending Layers chapter in the previous edition. These tutorials cover the theme of blending, placing, and composting things into images where they don't really belong and making them look realistic. This is an advanced chapter and makes the assumption that you have covered everything so far. Here you will replace a person's background, wrap graphics on uneven surfaces, use layers for lighting and shadows, and create the cover image.
