Layer Basics
Photoshop's layers can be thought of as separate films, much like transparency sheets. Each layer contains its own discrete contents. Individual layers contain objects which together create your composite image. The following document will introduce some of the basic concepts related to layers. For more information about layers, refer to Working with Layers or Advanced Layer Options.
Active Layer Tips
When you select a layer in the Layers palette, that layer is active. The following tips refer to active layers:
- Only one layer can be active at a time.
- The name of the active layer appears in the title bar of the image window.
- Changes affect only the active layer even though you view the whole image in the image window.
Hiding/Displaying the Layers Palette
The Layers palette is your essential tool for working with layers. It contains a list of all the layers, starting with the topmost layer. To the left of the name is a thumbnail of the contents of each layer. You can use the Layers palette to perform many tasks (e.g., create, delete, hide, merge, and flatten layers).
-
From the Window menu, select Layers
This action toggles the feature on and off.
NOTE: A check mark will appear in front of Layers when the Layers palette is displayed.
Hiding/Displaying Layers
You may find it useful to hide layers while working in Photoshop. For example, when merging layers, you can hide some layers so that they will not be merged. Visible layers have a VISIBILITY icon
next to them; hidden layers do not.
- On the Layers palette, for the layer(s) you wish to hide, click the VISIBILITY icon
HINT: To hide several layers at once, click and drag within the Visibility column. This action toggles the layer between hidden and displayed.
