Rearranging layers


The order in which the layers of an image are organized is called the stacking order. The stacking order of layers determines how the image is viewedyou can change the order to make certain parts of the image appear in front of or behind other layers.

Now, you'll rearrange layers so that the photo image is in front of another image that is currently hidden in the file.


1.

Make the Shell, Letter, and Paper texture layers visible by clicking the eye-icon boxes next to their layer names.

Now you can see that the photo image is partially blocked by these other images on other layers.

NoteThe Photo layer is also below the 2 text layer, which is at the top of the stack, but we'll leave that layer hidden for the moment. We'll get to it later in this lesson.

2.

In the Layers palette, drag the Photo layer up so that it is positioned between the Shell and Letter layerslook for a thick line between the layers in the stackand then release the mouse button.

The Photo layer moves up two levels in the stacking order, and the photo image appears on top of the letter and paper texture images, but under the shell and the "2."



You can also control the stacking order of layered images by selecting them in the Layers palette and using the Layer > Arrange subcommands: Bring to Front, Bring Forward, Send to Back, and Send Backward.

Changing the opacity and mode of a layer


Notice how the crinkled piece of paper is opaque, blocking the blue background in the layer below it. You can reduce the opacity of any layer to allow other layers to show through it. You can also apply different blending modes to a layer, which affect how the color pixels in the opaque image blend with pixels in the layers underneath. (Currently, the blending mode is Normal.) Let's edit the Paper texture layer to allow the background to show through.


1.

Select the Paper texture layer, and then click the arrow next to the Opacity box in the Layers palette and drag the slider to 50%. Or, type the value into the Opacity box, or scrub the Opacity label.

The Paper texture becomes partially transparent, and you can see the background underneath. Notice that the change in opacity affects only the image area of the Paper texture layer. The letter, photo, and shell images remain opaque.

2.

To the left of the Opacity option in the Layers palette, open the Blending Mode pop-up menu, and choose Luminosity.

3.

Increase the Opacity to 75%.

4.

Choose File > Save to save your work.


For more about blending modes, including definitions and visual examples, see Photoshop Help.

Linking layers


Sometimes an efficient way to work with layers is to link two or more related layers. By linking layers together, you can move and transform them simultaneously, thereby maintaining their relative alignment.

You'll now link the Photo and Letter layers, then transform and move them as a unit.


1.

Select the Photo layer in the Layers palette, and then press Shift and click to select the Letter layer.

2.

Choose Link Layers from the Layers palette pop-up menu, or click the Link Layers button at the bottom of the palette.

A link icon () appears next to both of the layer names in the Layers palette, indicating that they are linked.

Now, you'll resize the linked layers.

3.

With the linked layers still selected in the Layers palette, choose Edit > Free Transform. A transform bounding box appears around the images in the linked layers.

4.

Hold down Shift and drag a corner handle inward, scaling the photo and the letter down by about 20%.

5.

Then, with the pointer inside the bounding box, drag the photo and the letter images to reposition them down and to the left in the image window so that the montage resembles the following image.

6.

Press Enter (Windows) or Return (Mac OS) to apply the transformation changes.

7.

Choose File > Save.


Adding a gradient layer


Next, you'll create a new layer with no artwork on it. (Adding empty layers to a file is comparable to adding blank sheets of acetate to a stack of images.) You'll use this layer to add a semi-transparent gradient effect that influences the layers stacked below it.


1.

In the Layers palette, select the Paper texture layer to make it active, and then click the New Layer button () at the bottom of the Layers palette.

A new layer, named Layer 1, appears between the Paper texture and the Letter layer.

NoteYou can also create a new layer by choosing New Layer from the Layers palette menu or Layer > New > Layer on the Photoshop menu bar.

2.

Double-click the name Layer 1, type Gradient, and press Enter (Windows) or Return (Mac OS) to rename the layer.

3.

In the toolbox, select the Gradient tool ().

4.

On the tool options bar, make sure that the Linear Gradient button () is selected, and then click the small downward arrow to expand the gradient picker.

5.

Select the Foreground to Transparent swatch, and then click anywhere outside the gradient picker to close it.

You can list the gradient options by name rather than by sample. Just click the right-pointing palette menu button () on the gradient picker and choose either Small List or Large List. Or, hover the pointer over a thumbnail until a tooltip appears, showing the gradient name.

6.

Click the Swatches tab to bring that palette to the front of its group, and select a shade of green that appeals to you.

7.

With the Gradient layer still active in the Layers palette, drag the Gradient tool from the lower right corner of the image to the upper left corner.

The gradient extends across the layer, starting with green on the lower right and gradually blending to transparent on the upper left. The gradient partially obscures the paper texture and background below it, so you'll change its blending mode and reduce its opacity to partially reveal those images.

8.

With the Gradient layer still active, in the Layers palette choose Multiply from the Blending Mode pop-up menu and change the Opacity to 75%. Now, the Paper texture and Background layers show through the gradient.


Adding text


Now, you're ready to create some type using the Horizontal Type tool, which places the text on its own type layer. You'll then edit the text and apply a special effect to that layer.


1.

Deselect all layers in the Layers palette by clicking outside the layer names (drag to enlarge the palette to create a blank area, if necessary).

2.

Set the foreground color to black by clicking the small Default Foreground and Background Colors icon () near the swatches in the toolbox.

3.

In the toolbox, select the Horizontal Type tool (). Then, on the tool options bar, do the following:

Select a serif font from the Font pop-up menu (we used Adobe Garamond).

Select a font style (we used Italic).

Enter a large point size in the Size text box (we used 76 points), and press Enter (Windows) or Return (Mac OS).

Select Crisp from the Anti-aliasing pop-up menu ().

Select the Right align text () option.

4.

Click in the upper right corner of the letter area in the image window and type Scrapbook. Then, click the Commit Any Current Edits button ().

The Layers palette now includes a layer named Scrapbook with a "T" thumbnail icon, indicating that it is a type layer. This layer is at the top of the layer stack.

The text appears in the area of the image where you clicked, which probably isn't exactly where you want it to be positioned.

5.

Select the Move tool (), and drag the "Scrapbook" text so that the baseline aligns with the top right edge of the letter.
