If you start with a white paper with no layers, to create a backdrop, you need to add a tonal adjustment layer so that you can easily see the edges of the paper. You can't perform all these tasks with individual layers, but you can with composite layers.Īs an example, we show you how to create a backdrop for an image and then merge the layers into one image. These layers can then be copied and inserted into a new Photoshop document, where the composite layers serve as the basis of a new document.
You can merge layers that you've created and then use the composite layers. The Merge Down command is the key to creating powerful Photoshop documents. In the next section, we show you how to merge layers. Then use Photoshop's Merge Down command to create the desired effect. To create a good example of layers, create several overlapping pages in Photoshop, such as pages 10 to 15. However, the number of overlapping layers increases the processing time and file size. The maximum number of overlapping layers is 500, and the order in which they overlap determines the depth of the image, not the pixels. You can add as many pages as necessary by adding more overlapping layers. In this example, Loft Image and the three stacked layers serve as an infinite set of pages in a magazine that illustrates the concept of layers. Photoshop layers are like the pages of a book you can add more pages and move pages around. Three additional layers are stacked on top of Loft Image in the Layers panel. We've included a few good examples in this chapter.įIGURE 2-1: A minimum of 20 layers is recommended.įigure 2-1 shows a Photoshop document that contains a single layer, named Loft Image. Some are professionally produced, while others are basic how-to guides. There are lots of Photoshop tutorials on the Web.
