Creating a New Layer


Layers give you control over the design elements of your document, so Adobe's Photoshop makes sure you have plenty of them. You have the ability to create up to 8,000 layers. While that may be more layers than you would ever use in one single document, it guarantees that you have the creative options to carry your designs to any level you desire. To create a new layer, you must first have an open document. A new image in Photoshop has a single layer. If you have more than one document open, make sure the active image is the one you want to add a layer. You can quickly add a layer using a menu or button or add a layer and select options using a dialog box. You can select options to name the layer, designate it as a clipping group, or even change its color Blending mode, and Opacity.

Add Layers to an Active Document



Select the

Layers palette.

Click the

Layers Options button, and then click

New Layer .

TIMESAVER

Click the Create New Layer button on the Layers palette to quickly add a layer.

The new layer is inserted directly above the active layer.



Did You Know?


You can move a layer in the stacking order.
Press the Ctrl (Win) or (Mac) key, and then use the Left/Right Bracket keys ([ ]). The Left Bracket key moves the layer down and the Right Bracket moves the layer up.

You can hide all layers except the clipping mask layer and the layer it is clipped to.
Press the Alt (Win) or (Mac) key, and then click the layer's visibility icon ().

Add Layers and Select Options



Select the

Layers palette.

Hold down the Alt (Win) or Option (Mac) key, and then click the

Create New Layer button to open the New Layer dialog box.

Select the layer options you want:


  • Name.
    Enter the name of the layer into the Name box.


  • Use Previous Layer To Create Clipping Mask.
    Select this check box to use the image information in the previous layer to mask the elements of the new layer.


  • Color.
    This option lets you color-code your layers. Click the Color list arrow, and then select from the available colors.


  • Mode.
    Click the Mode list arrow, and then select from the available blending modes.


  • Opacity.
    This option controls the visibility of the new layer. Select a value from 0 to 100 percent.

Click

OK .



Did You Know?


You can control what layers the adjustment is applied.
To confine the effects of an adjustment layer to the layer immediately below, hold down the Alt (Win) or Option (Mac) key, and then click on the visible line separating the adjustment layer from the next lower layer.


For Your Information


Selecting Layer Options

When you create a new layer in Photoshop, the size of the file does not increase. It's only when you begin painting, or adding information to the layer that the size of the Photoshop document will begin to grow. For example, creating a blank layer in a document with a file size of 10 MB does nothing to increase the size of the file. However, opening a 10 MB file, and creating a copy of the original document layer, will create a file size of 20 MB. Layers are great creative tools, but you only want to use them when you need them. Remember, performance is directly related to the size of the active document file, and the bigger the file size, the slower Photoshop performs.
