Undo up to 50 times in Photoshop.
If you make a mistake or regret a change, you can undo (and redo) up to 50 times in Photoshop without running into any issues. However, once you save your project and close out the application, your changes will be permanent in most cases.
Work smart so you never lose a version.
When you edit using layers, each new change you make is laid on top of all the others. This makes it easy to experiment — if you decide you don’t like a set of changes, just remove those layers until you’re back to a version you like.
