UNDO A SAVE IN PHOTOSHOP CS2!

posted by pixelbase, Dec 31, 2006 6:44 PM — 21 comments

This is especially handy if you have flattened an image, saved it, and later realize that you need to change something in a layer.

This only happens to me about every other day.

If this happens to you, here's the keyboard shortcut to save your day: Mac: Apple - Option - Z; PeeCee: Control - Alt - Z.

Press these keys a few times and you will see your layers magically reappear in your layers palette.

Very slick!

Well, this is the option of going one step back , just remember that the default settings of PS is 20 steps back (increase them to make sure that you can always go back in time)

Ahmed, this tip is all about going "back in time".

However, this is not your typical "Undo" command (apple - z, or control - z), or going back in history, using the history palette (which is what I think you mean by the "20 steps back"), things that you can do all the way up until you save your doc.

After you save your doc, you can't use the "undo" commands (or make changes using the history palette).

However, any time AFTER you save your doc, you can use my tip to save your "donkey" should you decide to change your brain (or mind), afterwards.

Personally, I change my "Step backward" keystroke to Ctrl/CMD-Z (no Alt key). That way, instead of toggling the current and previous step, it behaves as I expect: it steps backward until I run out of history. It's more intuitive that way.

so long as you don't close the file you saved, i guess.

Jonathan, you guessed right! (And the crowd goes wild!)

oh boy, what a waste of my time! this is just a typical "undo" as Microsoft defines it! and you can always undo, even after you save the file...
On the other hand, what REALLY could be a day save is "REVERT." If you want to undo sooo many actions you can always revert to the last saved state regardless of how many actions down history (more than 100s) but watchout, once you revert, you cannot step forward! eh, LIFE

Sorry, Mariam, this is not "just a typical undo". A typical "undo" would be control > z (or command > z), which you can use all the way up until the time you save your file.

This "tute" (the urban dictionary defines "tute" as a slang word used by students at the Oxford University for "tutorial") is for anyone who does not know how to "undo" a change after they have saved a file in PS CS2, which is a different (and, in my opinion, not a typical undo) keyboard shortcut.

If you consider this "tute" to be a "waste" of your time, I have to assume that you already know how to undo a change after you have saved your file, because if you don't, a waste of time would be any time spent recreating a doc because you don't know how to undo a change AFTER you have saved it.

Yes, you can "always undo, even after you save the file", but not everyone knows how to do this in PS CS2. This "tute" is for people that don't already know how to do this in PS CS2.

PS CS2 is an "Adobe" product, so I'm not entirely sure why you are using "Microsoft" to define a PS CS2 undo, or what you mean by "Microsoft's" definition of undo.

A dictionary definition is, "the reverse effect of a computer command: "to cancel the effect of the last command or action done on a computer, restoring the material being worked on to its previous condition".

This definition does not say anything about undoing any commands after you have saved the file.

Yes, another useful tool is "Revert" (Choose File > Revert), which reverts to the last saved version. Revert is added as a history state in the History palette and can be undone, however, I this is not the same thing as undoing after a save (which is what this "tute" is about).

It is a regular command that Ctrl+Z for single Undo and Ctrl+Alt+Z for Multiple Undo (Depending on number of Undos defined in preferences).

Now excuse me pixelbase...Do you know what does your tutorial heading mean?

Half an hour ago I did it: saved the final version on the original photo...

Way past the 20s steps limit.

Just went to to the original image (first step) , which is always available, and saved it under a new name.

Do you mean to tell me you can save and close a photo, open it back up and STILL get your layers back? I love you!!!

I wanted to test this to see exactly what it did since there seem to be a lot of people missing the extra key you hit when you do it (compared to a "regular undo").

First, I tried a ps doc that I had saved and closed. Nothing happened, when I tried the command. No real surprise there, but that sucks for those who understood the tut that way.

Then, I tried a ps doc that I had saved and not closed. Not a lot different from a regular undo.

The good that came out of this: I actually bothered with the preferences and know that I'm not limited to 20 states in my history.

This isnt what the title advertises.

Ctrl + Z = undo once, hit it again and it will redo what you undid!

Ctrl + Alt + Z = Keeps undoing steps.

F12 = Goes back to last saved state.
