Chapter 4. Editing Photos > Undoing Changes

Undoing Changes

We all make mistakes, and that’s certain to happen on occasion when you’re working with your photos too. With digital photos, though, your changes aren’t irrevocable.

Ways to undo changes to a photo:

  • After you’ve performed an action, to undo just that action, choose Undo from the Edit menu (). Keep choosing Undo to continue undoing earlier actions.

  • To remove all changes from a photo, select it and choose Revert to Original from the File menu, or -click the image and choose Revert to Original from the contextual menu. iPhoto warns that you’ll lose all changes to the photo (Figure 4.38).

    Figure 4.38. To revert to the original version of an image after making a number of edits, select it and choose Revert to Original from the File menu. iPhoto warns you that you’ll lose all your changes.

Tips

  • To see what the photo would look like if you were to undo a change, press . You must still choose Undo if desired.

  • iPhoto modifies the Undo command in the Edit menu to reflect your last action, so it may say Undo Crop Photo, for instance.

  • If you edit in the image-editing window, you can undo changes you make in that window only as long as it remains open.

  • Anything you can undo via the Undo command, you can Redo via the Redo command in the Edit menu.

  • Revert to Original works even if you edit a photo in another program—iPhoto starts tracking the original as soon as you double-click the photo. However, don’t drag a photo from iPhoto to the Dock icon of another program to edit it; if you do so, iPhoto can’t track the changes.


Recover Original

It turns out that Revert to Original isn’t doing anything particularly hard. When you edit a photo, iPhoto makes a copy of the original in a folder called Originals that lives in the same directory as the image. As long as this happens, you can recover the original image no matter what might go wrong.

You can find your original images by sorting through the iPhoto Library’s sub-folders manually, or you can select the desired image in iPhoto and use the Show Image File AppleScript script to display it in the Finder, after which you can find the original in the related Originals folder. (The script is available at www.apple.com/applescript/iphoto/.)
