Chapter 5: Using layers
Layers are useful because they let you add components to an image and work on them one at a time, without
permanently changing your original image. For each layer, you can adjust color and brightness, apply special effects,
reposition layer content, specify opacity and blending values, and so on. You can also rearrange the stacking order, link
layers to work on them simultaneously, and create web animations with layers.

Creating layers
Understanding layers
Layers are like stacked, transparent sheets of glass on which you can paint images. You can see through the transparent
areas of a layer to the layers below. You can work on each layer independently, experimenting to create the effect you
want. Each layer remains independent until you combine (merge) the layers. The bottommost layer in the Layers
panel, the Background layer, is always locked (protected), meaning you cannot change its stacking order, blending
mode, or opacity (unless you convert it into a regular layer).

Transparent areas on a layer let you see through to the layers below.
Layers are organized in the Layers panel. It’s a good idea to keep this panel visible whenever you’re working in
Photoshop Elements. With one glance, you can see the active layer (the selected layer that you are editing). You can
link layers, so they move as a unit, helping you manage layers. Because multiple layers in an image increases the file
size, you can reduce the file size by merging layers that you’re done editing. The Layers panel is an important source
of information as you edit photos. You can also use the Layer menu to work with layers.

Ordinary layers are pixel-based (image) layers. There are several other layer types you can use to create special effects:
Fill layers
Contain a color gradient, solid color, or pattern.
Adjustment layers
Enable you to fine-tune color, brightness, and saturation without making permanent changes to
your image (until you flatten, or collapse, the adjustment layer).
Type layers and shape layers
Let you create vector-based text and shapes.
You can’t paint on an adjustment layer, although you can paint on its mask. To paint on fill or type layers, you first
convert them into regular image layers.
