Lesson 1. Getting to Know the Work Area > Undoing a single action

Undoing a single action

Even beginning computer users quickly learn to use and appreciate the familiar Undo command.

Select the File Browser button () on the tool options bar, and use the Folders palette to find and select the Lessons/Lesson01/Project3 folder.

In the thumbnails pane, select the 01End3.psd file so that you can see the results you’ll achieve in this lesson. Then, select and double-click the 01Start3.psd file to open it in Photoshop. Close the File Browser.

Notice the listings in the Layers palette. The layers structure includes a clipping mask, which works somewhat like a selection, restricting the area of the image that can be altered. With the clipping mask in place, you can paint a design over the man’s tie without worrying about any stray brush strokes disturbing the rest of the image. The Tie Designs layer is selected, because it’s the layer you’ll be altering in this project.

In the toolbox, select the Brush tool (), or press B to select it by its keyboard shortcut.

On the tool options bar, select the Brushes tab in the palette well to temporarily open the Brushes palette.

Scroll down the list of brushes and select the Soft Round 35-pixels brush. (The name will appear as a tooltip if you let the pointer hover over a brush.)

If you want to try a different brush, that’s OK, but for this task select a brush that’s reasonably close to 35 pixels—preferably in the range between 20 and 50 pixels.

Move the pointer over the image so that it appears as a circle with the diameter you selected in Step 5. Then draw a stripe anywhere in the yellow tie. You don’t have to worry about staying within the lines because the brush won’t paint anything outside of the tie clipping mask.

Oops! Your stripe may be very nice, but the design calls for dots, so you’ll need to remove the painted stripe.

Choose Edit > Undo Brush Tool, or press Ctrl+Z (Windows) or Command+Z (Mac OS) to undo the Brush tool action.

The tie is again a solid yellow color, with no stripe.

You’ll get more experience with clipping masks when you do the project in Lesson 10, “Vector Masks, Paths, and Shapes” and Lesson 11, “Advanced Layer Techniques.”
