Are you sure the history steps are not there, just grayed out and very dim?
If you closed the file, then the history is indeed gone forever.
Nope, theyre definitely not there, I dont see how for such an advanced program, doing something so simple like clicking a snapshot can just delete your work.
Well i saved it and closed it after it happened, does that mean I'm doomed? Once again, I just dont get how? And im surprised how this doesnt happen to everyone when they first start out
The clicking on the snapshot did not delete a thing. Not even saving the file, but…
…closing the file did!
Sorry to say, yes, you're "doomed", as you put it.
You should go through the link mentioned below to know more about history and undo, It might help you in future.
Also, You can increase history states.
Go to 'Edit' > 'Preferences' > 'Performance' > 'History and Cache' > History states:
thanks for answering!
even before i closed the file it all looked the same though, how would I have been able to recover it?
Before closing the file, all your History steps would have been there, intact, only the steps in the History Panel would have been grayed out, very light and dimmed. You would have been able to just click on the last of such dimmed steps and you would have returned to the step right before you clicked on the snapshot, thereby recovering all your work.
The moment you close the file, however, all those dimmed steps are discarded and you cannot retrieve them.
Try it if you're still doubting. It's easy enough to test.
it would have been easy for me to retrieve the steps if they were lightly grayed out. the point is all the steps just vanished :/
There's no way I can replicate that just by clicking on a snapshot, but that's what will happen if you click on File > Revert or press F12.
Just clicking a snapshot does not clear your history.
But doing something else to the image after clicking the snapshot does.
If you've just gotten yourself in this condition, you have one last gasp thing you can do: Edit - Undo.
1. You do a lot of work and have a lot of History states.
2. You click a snapshot. Your entire history is grayed out, but still there.
3. You accidentally do something like Control-A (select all). Boom, your history is gone, replaced by "Select Canvas".
4. If you DON'T DO ANYTHING ELSE AT THIS POINT, you can still get back... Choose Edit - Undo. Your history now looks again like it did in step 3. Click on the last state and you'll be back to where you were in step 1.
Your best bet is to learn to save your work occasionally.
This is the reason why versioning is such a great idea: you will not lose your file history, and every change is safely stored away in a new file. You never know what will happen: this time you clicked on the wrong button, the next time the power is out. Net effect: all work lost.
Read this article about versioning:
You might want to invest in something like http://pixelnovel.com/timeline/features
Aside from that, save often, and save in new versions. That way you can always retrieve a slightly older version, and it prevents you from losing your work.
And I would avoid Adobe's Cloud Drive thingy like the plague.
We use Subversion here at ProDigital Software to allow us to maintain a history of revisions of everything we work on.
Another couple of options for the individual user that can help keep a history of what you've done are Apple's Time Machine or Microsoft's File History. But you do have to remember to save a master file from Photoshop occasionally.
Photoshop's own Auto Save, in the most recent couple of versions, does help, but there's no substitute for saving your work.
Netbeans has a really nice local file history built-in - I wish this type of feature would be integrated in applications like Photoshop as well. Heck, any application would benefit from that.
