5. Quickly Mask Part of Your Image
Sometimes you have a picture of a person or an object that’s in front of a confusing background, and you’d really like to see that person without the clutter. Preview has two nifty features that let you do this—Instant Alpha and Extract Shape. To use the first, open a picture and then click and hold the Select button in Preview’s toolbar. From the menu that appears, choose Instant Alpha. Next, click and drag to remove background areas of the image. Start by dragging small areas to see how Preview expands the selection. You don’t have to get everything in one pass—just click and drag again to add to your selection. If you make a mistake, press the escape key to remove the selection altogether or option-drag to deselect particular areas. When you’ve highlighted everything you want to remove, press return to crop the background from your picture.
Using Extract Shape is even easier. Choose it from the Select button menu, and then start drawing a line around the item you want to retain in your picture. As you do this, a thick red line follows your cursor. Make sure to draw entirely around the item you want to keep; continue until you’ve joined the beginning and end of your line. You’ll then see a number of handles on the line. Move any of these if you need to improve part of your outline. Don’t worry about drawing perfectly. The magic starts when you press return—Preview calculates what to keep, and removes your picture’s background. In many cases, you’ll be able to crop out all the dreck the first time, though with some pictures you may need to repeat the process a couple of times.

1. Annotate PDFs
One of the best things about Adobe’s Portable Document Format (PDF) is that it allows you to share documents while making sure that everyone sees the same layout, even if the recipients don’t own the software that created the document. You can create PDF files from the Print dialog box of any Mac OS X program and then send them to friends and colleagues. In the past, if you had detailed comments about the PDFs your colleagues sent you, you were stuck—you couldn’t change the text, so you had to put your suggestions in another file, such as an e-mail message. Alternatively, someone in your group had to buy a copy of Adobe’s $449 Acrobat Professional 8 () to allow you all to add comments directly to the file.
But Leopard’s Preview lets you add notes, highlight and strike through text, or use ovals and rectangles to call attention to specific sections of the page. You can even add links to other pages in a document or to Web sites. Best of all, other PDF readers—in -
