Adobe Photoshop CS2 CLASSROOM IN A BOOK [Electronic resources] نسخه متنی

1.

If the Layers palette is not visible in the work area, choose Window > Layers.

There are five layers listed in the Layers palette for the 06Start.psd file (from top to bottom): a text layer called 2, Shell, Letter, Paper texture, and Background.

2.

Click to select the Background layer to make it active (if it is not already selected). Notice the layer thumbnail and the icons on the Background layer level:

The lock icon () indicates that the layer is protected.

The eye icon () indicates that the layer is visible in the image window. If you click the eye, the image window no longer displays that layer.

Use the context menu to hide or resize the layer thumbnail. Right-click (Windows) or Control-click (Mac OS) on a thumbnail in the Layers palette to open the context menu, and then select No Thumbnails, Small Thumbnails, Medium Thumbnails, or Large Thumbnails.

The first task for this project is to add a sepia-toned photo to the scrapbook montage. You will retrieve it now.

3.

Click the Go to Bridge button () on the tool options bar, and in the Lesson06 folder, double-click the Photo.psd file to open it in Photoshop.

The Layers palette changes to display the layer information and a thumbnail for the active Photo.psd file. Notice that here is only one layer in the Photo.psd image: Layer 1, not Background. (For more information, see "About the Background layer" on the following page.)

About the Background layer

When you create a new image with a white or colored background, the bottom layer in the Layers palette is named Background. An image can have only one background. You cannot change the stacking order of a background, its blending mode, or its opacity. You can, however, convert a background to a regular layer.

When you create a new image with transparent content, the image does not have a Background layer. The bottom layer is not constrained like the Background layer; you can move it anywhere in the Layers palette, and change its opacity and blending mode.

To convert a background into a layer:

To convert a layer into a background:

Note:
You cannot create a background by renaming a regular layer Background. You must use the Layer From Background command.

1.

In the Layers palette, double-click the name Layer 1, type Photo, and then press Enter (Windows) or Return (Mac OS). Keep it selected.

2.

If necessary, drag the Photo.psd and 06Start.psd image windows so that you can see at least part of both images onscreen. Then, select the Photo.psd image so that it is the active file.

3.

In the toolbox, select the Move tool () and position it over the Photo.psd image window.

4.

Drag the photo image and drop it into your 06Start.psd image window.

The Photo layer now appears in the 06Start.psd file image window and its Layers palette, between the Paper texture and Background layers.

5.

Close the Photo.psd file, and do not save your changes to that file.

If you hold down Shift when you drag an image from one file into another, the dragged image automatically centers itself in the target image window.

1.

Click the eye icon () for the Photo layer to hide the photo.

2.

Click again to reveal it.

1.

Make sure that the Photo layer is selected. (To select the layer, click the layer name in the Layers palette.)

The layer is highlighted, indicating that it is active.

2.

To make the opaque areas on this layer more obvious, hide all layers except the Photo layer by holding down Alt (Windows) or Option (Mac OS) and clicking the eye icon () for the Photo layer.

The blue background and other objects in the start image disappear, and the photo appears against a checkerboard backdrop. The checkerboard indicates transparent areas of the active layer.

3.

Select the Magic Eraser tool (), hidden under the Eraser tool ().

Now you will set the tolerance for the Magic Eraser tool. If the tolerance is too low, the Magic Eraser tool leaves some white remaining around the photo. If the tolerance setting is too high, the Magic Eraser tool removes some of the photo image.

4.

On the tool options bar, set the Tolerance value either by scrubbing the Tolerance label or by typing 22 in the Tolerance text box.

5.

Click the white area around the photo in the image window.

The white area is replaced by the checkerboard, indicating that this area is now transparent.

6.

Turn the background back on by clicking the eye-icon box next to its name. The blue scrapbook background now shows through where the white area on the Photo layer has become transparent.
