To undo a "reverse" (meaning to revert an action or go back one or more steps) in Photoshop, you primarily use keyboard shortcuts or the History panel. Here's how:
Undoing Actions
Single-Step Undo:
- Windows: Press
Ctrl + Z - Mac: Press
CMD + Z
This will undo the very last action you performed. Repeatedly pressing this combination will toggle between the last state and the state before it.
Multiple-Step Undo:
- Windows: Press
Ctrl + Alt + Z - Mac: Press
CMD + OPT + Z
This allows you to step backward through multiple actions in your editing history. Each press will undo another previous step.
Redoing Actions
If you've gone too far back and want to redo an action, use the following:
- Windows: Press
Ctrl + Shift + Z - Mac: Press
CMD + SHIFT + Z
This steps forward through your history, redoing actions you previously undid.
Using the History Panel
The History panel provides a visual representation of your editing steps and allows for more precise undo/redo functionality.
- Open the History Panel: Go to
Window > History. - Navigate Your History: The panel lists all your actions in chronological order. Click on any state to revert your image to that point. Steps listed below your selected state will be undone. Clicking a later state will redo actions.
- Adjust History States: You can control how many history states Photoshop saves by going to
Edit > Preferences > Performanceand adjusting the "History States" value. A higher value allows more undos but requires more memory.
Example Scenario
Let's say you performed these actions:
- Added a layer
- Applied a filter
- Made a color adjustment
To undo the color adjustment, you would press Ctrl + Z (Windows) or CMD + Z (Mac) once. To undo both the color adjustment and the filter, you would press Ctrl + Alt + Z (Windows) or CMD + OPT + Z (Mac) twice. To redo the color adjustment after undoing it, you would press Ctrl + Shift + Z (Windows) or CMD + SHIFT + Z (Mac). You could also use the history panel and click on the state prior to adding the color adjustment.
