Restoring layer operations to the Adobe Photoshop program is the same as restoring a file from the changes made, however, it is not always possible to do this, since the program's memory stores a limited number of operations.
Necessary
Adobe Photoshop program
Instructions
Step 1
Open the toolbar in Adobe Photoshop, which contains information about the operations you performed. To do this, open the "Windows" menu in the top panel of the graphical editor and check the "History" item. After that, in the lower right corner you should have a new additional window with two tabs - "History" and "Operations" (History / Actions in the English version of Adobe Photoshop).
Step 2
Select the first one and view the history of changes with the current file. In order to restore the layers, return the work done on the file to the desired level, at which all the layers were in place.
Step 3
Also use an alternative undo method to revert layers in Adobe Photoshop. To do this, while in the editing menu of the current image, press the Shift + Ctrl + Z or Alt + Ctrl + Z key combination to switch to returning or repeating an action performed over the image.
Step 4
You can also do this from the main menu of the document by using the "Undo action" and "Redo action" item in the "Edit" section of the program panel at the top. This method is not as convenient as the first one, since you cannot view the entire history of changes, by which it is much easier to navigate and return the editing of the picture to the desired position.
Step 5
Set the maximum number of operations stored in memory in the memory of Adobe Photoshop, this will help you if you often perform a lot of actions on images, and their sequence contains too many items to be stored in memory at the default settings. This is done in the memory settings in the "Edit" menu. You can change the number of steps memorized by the program up to 1000, but keep in mind that Photoshop will use more system resources.
