How to redo undone actions in Photoshop when other actions have been done

Question

I went to History in Photoshop and did a couple of undos. After that I wish to redo, however I accidentally did another action so now I can't step forward.

Is there a way to recover my losses? Something like reset back to whatever it was 5 minutes ago would be more than wonderful.

Answer 1

As far as I know techie007 is correct but I have a work around.

You will need to create an Action to do this.

Create a New Action. (make sure it is recording when doing the next steps)

Make the first step a "Snapshot" of your document (you want full document snapshot)

Then make your next step a undo.

Now when you undo use the action instead of CTRL-Z

The only downside to this is everytime you undo you make a snapshot. Very RAM intensive if you do a lot of undos.

I made a video of the steps. Hope the video makes sense => Video Here

Update I found this out since I posted:

You can try non linear in the history options, but it can be confusing because it works totally different from linear history states. Learn More Here, Here, and Here.

Answer 2

As far as I know, Photoshop's Undo/Redo is a single (indexed) stack structure; so you can't do what you want.

Your best (only?) chance is probably to reload your last save point, from disk.
