Controlling Image Information Using the Layers Palette
When you work on multi-layered documents, it's important to understand the ways Photoshop gives you to control image information. For example, working on a document that contains 20 layers is a difficult proposition. Fortunately, Photoshop gives you control over the document, everything from layer names to locking pixel information is available in Photoshop's bag of image-control tricks. When linking two layers together, you can move or resize the layers at the same time, thus saving valuable time. Let's explore some of the ways you can control image information on the Layers palette.
Control Image Information
Select the Layers palette, and then use one of the following options:
Layer Name.
To name a layer, double-click on the current layer name, type a new name, and then press Enter (Win) or Return (Mac).
Show/Hide.
To temporally hide or show a layer (make its contents invisible or visible in the document window), click the Eyeball button, located in the Show/Hide box.
Linking.
To link two or more layers, hold the Shift key and click the layers you want to link, and then click the Link Layers button (
) (located at the bottom left of the Layers palette). The link icon indicates the layers are linked. Linking lets you move or resize the layers as a unit.
Locking.
The four available locking options are Lock Transparent Pixels, Lock Image Pixels, Lock Position, and Lock All.
Stacking Order.
To change the position of a layer in the stack, drag the layer up or down. A dark line appears as a visual cue to indicate the new layer location.
