In this example I have shown how the clone stamp tool can be used to paint detail from one part of an image onto another. Note how the retouching is applied to an empty new layer and the Sample Current Below layers option was selected in the Options bar. 45 Martin Evening Adobe Photoshop CS4 for Photographers Blending modes Photoshop image layers can be made to blend with the layers below them using any of the 25 different blending modes. Layer effects styles allow you to add effects such as drop shadows gradient pattern fills or glows to any layer. Custom styles can be loaded from and saved to the Styles panel. Working with Layers Photoshop layers allow you to edit an image by building up the retouching and added bits in multiple layered sections such as in the example shown in Figure 1.56. A layer can be an image element such as a duplicated background layer a copied selection made into a layer or content that has been copied from another image. Or it can be text or a vector shape layer. Or lastly these are adjustment layers which are like image adjustment instructions applied in a layered form. Layers can be placed together in groups which makes the layer organization easier to manage and you can apply masking to the contents of a layer with either a pixel layer mask or a vector mask. You will find plenty of examples throughout this book where I show you how to work with layers and layer masks. Figure 1.56 The above Layers panel shows the layer contents of a multi-layered Photoshop image. The diagram on the right shows the image that this Layers panel view refers to where the layers have been pulled apart. 46 Chapter 1 Photoshop fundamentals Automating Photoshop Why spend more time than you have to performing .
