iPhoto gives Mac users the opportunity to edit their digital images and save them to their hard drive. Crop a photo, change the coloring or fix imperfections in just a few seconds. Create multiple versions of the same image to give yourself options by created a duplicate, or copy, of your original image before you begin the editing process. Creating a duplicate takes just seconds and gives you a back up in case you change your mind later about the photo alterations you make.
Click on "Events" in the "Library" section of the sidebar to locate a photo based on when it was taken. Click on the "Key Photo" that represents an event to open the rest of the images in the folder. Click on "Photos" in the sidebar to browse all images at the same time.
Click once on the image to be copied.
Select "Photos" in the menu bar and then "Duplicate." Alternatively, hold down the "Command" key at the same time as the "D" key.
