PDF PDF : LAYERS PHOTOSHOP STUDIO WITH BERT MONROY : DIGITAL PAINTING Layers What Layers Are All About Layers were introduced in Photoshop 3 (1994) and are perhaps the program’s most valuable tools. They serve a myriad of pur- poses. In this document I’ll outline their functionality. I refer to layers extensively throughout the book since they are inevitably where all aspects of an image are created. A Photoshop document can have as many layers present in the document as memory will permit. Each of the layers contains parts of the overall image. These layers can be manipulated individually in as many ways as you desire without affecting the rest of the image. Excerpted from Photoshop Studio with Bert Monroy: Digital Painting by Bert Monroy.
