Record Every Single Step You Do Using Photoshop’s History Log
If you want a text record of every single step you’ve done in an image, then turn on Photoshop’s History Log.
Press Ctrl K (Mac: Command K) to bring up the Preferences panel. In the History Log tab, click on the History Log check box. Then click Text File, and choose a location to save the file and give it a name.
You can now start working on your image and Photoshop will record every step you take. To review the steps, find the text file and double click on it.
