One benefit of non-destructive editing is that you can always throw away your edits and go back to the original if you don't like how the photo turned out, or if you just want to play around with colors or effects.
Reset All button
While you're in the editor, click the Reset All button to return to the photo's original state.
Click the Cancel button to return to the library without applying any edits. In the confirmation dialog that appears, click the Don't Save button to discard the edits (Figure 4.14). Or, click Continue Editing to stay in the editor.

Suppose you made some crazy edits late at night and decide to undo the damage the next day. You could open the image in the editor, click Reset All, and end up with the original picture. Or you could make the change without entering the editor at all.
Simply click the Photo Options pop-up menu and choose Revert (Figure 4.15). Any edits are removed.
