In the Photo Browser, select multiple photos of the same subject in the same pose. Choose View > Photo Compare. Use the navigation buttons to view your photos side by side.

Photo Compare displays two photos next to each other. To decide which is better, you can zoom in on both photos at the same time and compare the small details. You can cycle through a set of photos, freezing the best shot and continuing through the photos.

Right-click the photo and choose Attach Tag > Favorites (or 5 Stars, 4 Stars, or other star rating) from the context menu. Click the Exit button (the dark circle with an “x”) when you finish.

With the photos still selected in the Photo Browser, choose Edit > Stack > Stack Selected Photos. You can also choose the command by right-clicking one of the selected photos and choosing Stack > Stack Selected Photos from the context menu.

Stacking gives you easy access to the photos because they are in one place in the Photo Browser, not scattered across rows. By default, the most recent photo is at the top of the stack. Don’t worry if this isn’t the photo you want at the top. In step 5, you’ll learn how to make your favorite photo the topmost.
