5.1 Basic Concepts of Layers

Layer is the term used to describe the different levels at which you can place an object or image
file. In the program you can stack, merge or define layers when creating a digital image. Layers
can be partially obscured allowing portions of images within a layer to be hidden or shown in
a translucent manner within another image, or you can use layers to combine two or more
images into a single digital image. For the purpose of editing, working with layers allows you
to go back and make changes within a layer as you work.
Use of layers is one of the most powerful and important features of Photoshop which makes it
a superior photo composition and retouching product. Layers concept is easy to explain once
you visualize how layers work. You can consider a layer as an image placed on transparent sheet
which you can lay on another transparent one. Each layer is a separate image which can be
modified independently without affecting images from other layers. The final image (which we
see) is a view of the layer stack from the top down.
