The new Aperture 3 gives you powerful yet easy-to-use tools to refine images, showcase your photography, and manage massive libraries on your Mac. It's pro performance with iPhoto simplicity.The fun begins even before you finish importing your photos. Double-click thumbnails in the Import window to view images, play videos, and hear audio files before they're fully imported. If you're on a deadline, you can begin adjusting an image even if it's still being copied from your memory card to your Mac.
