Most people use their history menu in Photoshop to undo things or restore a document to a previous state, but did you know that you can actually jump back in time with the history menu, keeping your current document intact? Non-linear history allows you to do just this!
Here’s how it works:
Open up your history menu, by clicking the History Menu Tab or from your Main Menu, use –>Window –> History. Once you have your History Menu active, go into the upper right corner and click the little options icon. This will open an options menu to select “History Options” Click on this option. This will open your History Menu options. Review the options that are checked and ensure that “Allow Non-Linear History” is checked. Once satisfied, choose “OK.”
Turning this feature on, allows you to work on any stage of the document without disturbing the other saved history. So for instance, if you like the current stage you have with your document, but want to restore something from a previous stage, you can now jump back in history and it won’t actually destroy anything you’ve done on your current document.
Have fun!
