Lightroom is a great photo editor, but sometimes you need to undo a last action. Here’s how to do it:

  1. Open Lightroom and click the three lines in the top left corner of the main screen. This will show a list of all the actions that have been performed in Lightroom this session.
  2. Click the undone action you want to undo. This will take you to a screen where you can select a new action to take place instead of the original one that was undone.
  3. Click OK and your photo will be updated with the new action taken instead of the original one that was undone.
